I'm generally happy with what I've bought from Modern Chess. The updates to some of the databases are a nice extra service. Though it's slightly annoying that the updates are typically web-only and not added to the pgn downloads. You would have to save the updates manually to have them available offline.

Regarding GM Chatalbashev on the delayed Benoni, I actually enjoyed it quite a lot, he reveals many move-order nuances/differences between the Late Benoni and Modern Benoni proper and I truly believe that if one truly grasps the material this could be a terrific point scorer at club and tournament level. Granted Chatalbashev may not be as organised as some of the other authors, but the quality of the actual material presented more than makes up for it.
I picked up this one as a useful surprise weapon. Lots of good material, but one big problem is coverage of one of the most critical lines, where White plays Bd3 and allows ...Bg4, is inexplicably brief.
Chatalbashev comments: "If White decides not to spend time on h2-h3, then the resulting positions are rather dry, both sides do not have big chances for a win..." But anyone who looks at a database and at Rios' excellent annotations to Spassky-Fischer, Sveti Stefan/Belgrade m (26) 1992 in his book
Chess Structures will realize that's an understatement of how dangerous this line is for Black. I must admit I wonder if Chatalbashev is intentionally downplaying that...
In fairness, the line Chatalbashev actually gives (though too briefly) is probably better than what Fischer played.
