Choose an electronic chess board

Hi everyone, 

I'm looking for an electronic chess board to improve myself and also to play with my 6yo son.
I just want a board with some computer evolution so i can learn from my mistakes. Also some abilities to hint one player during the game (so my son is able to understand his own mistakes). I don't need a too strong computer, i'm not even 1000 ELO yet.  
I think I have a budget under 200$/€. 

I saw the lexibook boards but i didn't find specific reviews online.
Thanks 

I looked for you but I see nothing but junk. I also found bad reviews on the Lexibook Elite. I have an old chess computer I really like but I never use it anymore. I use Droidfish with a vinyl board and plastic pieces. Shredder might be easier to find and friendlier to use. Chessnut Air looks promising to me, but I don't think I'll get it because a GUI and vinyl board work well enough together.

@greginos

I think the Millennium ChessGenius Pro may be right for you.

Note that it's not an online board, however

It sounds like the Chessnut Air would fit your needs.  There's a rather extensive thread on it in the CBE forum, and the overwhelming opinion is positive. They are running a sale at the moment, so it brings the cost down ro your desired price point.

I agree with the comment above by Boydcarts. Chessnut Air or if you want a tournament sized chess computer, then maybe Square OFF Pro. I don't think you would want to spend around $100 on those low quality chess computers as I heard they aren't as durable or great. As BoardMonkey pointed out, most of them are junk. Perhaps, you could try the used 1990s chess computers for the $100 price range as they were much more better built then the modern ones today that's about in the $100 price point range. But I think you would be better off spending more money and getting a better modern chess computer like Square Off Pro or Chessnut Air instead. They offer better software and hardware options then old chess computers and their price isn't too high like some of the other higher end chess computers today.

Do you want a stand-alone chess computer?

The Square Off Pro and Chessnut Air are not actually chess computers--rather they are input devices that you use together chess software running on a mobile device or PC.

Thank you for all you good remarks. 
I'll look for the chessnut air, i thought the millenium was a little bit small but I have to see it with my own eyes to be certain.

@aernout_nl, yes if possible. I don't progress the way I want with the bots from chess.com

Interesting. What make you think that you will progress from a chess computer better than from the Chess.com bots? (Not that it matters for your question.)

The bots are very specific / use case oriented (queen early attacks, openings or finale). I can beat robots around 1200 to 1500 but I'm stuck between 700-800 ELO. So I think with a dedicated computer, it would be easier. Maybe I'm misleading.

Honestly, if your thinking about the best chess computer for learning purposes, I think currently chessup offers the best options for new players because it actually shows which moves would be good and which moves would be bad upon touching the pieces, during games against the engine. It however doesn't tell you why such moves are bad. I didn't mention it earlier because it's past the budget range you allocated. But if I am to be honest with you, I don't think you need a chess computer at your 1000 elo level. I would instead just recommend that you read this book called "How to Reassess your Chess," by Jeremy Silman. All you need is that book, how to read algebraic chess notation and a normal chess set to play out the moves from that book for analysis purposes. Take your time and learn the strategies of positional play and by the time you finish that book, you will see that you had improved. Lol. I never bothered finishing the book myself. Specially didn't focus on the endgame studies which is why my endgames tend to be usually weaker then my opening and middle games. But I find myself too lazy to do so much of the reading. 

Hi greginos

I confirm the book recommendation. Buy this book and a cheap chess set. This combination was my start in the chess world, too.

Look for a chess club in your area for yourself and your son. In our chess club we have some father and son members.

Good luck.

Thank you both for your recommandations, I'll look for this book.
