I have the SimpleStereo board, which is dual pokey, covox, and AKI keyboard interface, I would recommend you get that if you're going to do stereo. I have the 128k of 130XE compatible RAM and 1MB of SatanTronic extended RAM, internal SIO-2-PC USB edition, internal MyIDE, Happy 1050 upgrade, S-Video with a upgraded video circuit, I was in line for a VBXE but I got really sick and was off the net for a few months and so lost the one put aside for me. Anyway, you will find that the form factor of the XEGS is actually quite useful more often then not, as you can use the keyboard at a distance with ease. The only thing you can't do with the XEGS is fit the multi-os upgrade from AtariMax, although I'm sure some day that will change and I can't use it anyway as my MyIDE is plugged where it would go.
