I used the CT-Art software fairly extensively. I went through all 1209 problems once. I repeated levels 10-40 (the first 821 problems) until I was very good at them. It's all chronicled at my old blog (thebackrank.blogspot.com). I am a 1700+ USCF rated player and found a good percentage of the level 40 problems challenging and the difficulty gets more above that.
These were my stats through level 80 the first time through the problems:

You should also be aware that as the problems get more difficult there are more flaws in the solution. Here is an account of all the errors I found in CT-Art:

There's no software subforum, so I guess posting under book and equipment makes the most sense.
I've been hearing good things about Convekta's CT-ART tactics training software for years, but I've always been content to do puzzles from books instead. I've recently discovered the joys of studying chess on a computer, which I very much prefer to books these days. I've been doing tactics puzzles at the usual web sites (emrald.net, chesstempo.com), but I know that doing puzzles that were chosen by a professional coach for their instructional value is better than just doing tons of random puzzles. So I've decided that I'll probably buy CT-ART for focused tactics puzzles.
) seems like the best bet for beginners and low level players.
Shopping around, I found that not only does Convekta's web site have the cheapest price I could find ($25), but they've also got big sales going on right now on some of their other items. For instance, their "Total Chess Training" packages that include 5 different programs are only $42.50 for download or $50 on DVD. The first of those comes with CT-ART, along with Encyclopedia of Opening Blunders, Encyclopedia of Middlegame, Strategy 2.0, and Studies 2.0. For that price, I'm considering getting that one. I can probably live without the opening blunders thing, but the others look potentially useful, especially the endgame studies, and the cost is only $17.50 more than buying CT-ART by itself.
So does anyone have any experience with any of these products? Any recommendations?
In case anyone else is considering buying any of these, I feel I should point out that I found several reviews stating that Convekta products don't work on Windows Vista. Also, the "Total Chess Training III" (if it's total, then why do they need 3 of them?
