I haven't seen anything on the net about these. Months ago I seem to remember someone mentioned playing the RS2200X about 5 games and he was about a 2100 player who beat it most of the time, if I remember correctly. I have the 2150L, which has 8 sets of levels (total of 64): a-h and 1-8 respectively. Against level d1 thru d5 I could win and would estimate as a "D" player. Against c1 thru c3 I could win but it was tougher. Level a1 and a3 (default) would always beat me, but lost to decent expert or "A" programs. I think h8 was the toughest level. Mark Loftus
