I love my u1541-II! its fantastic. I just wish it could load my warpspeed2 c128 image when in my c128
other than that, fanstastic.
Ive heard good + bad from chameleon. its no good standalone because it has no joystick so you ned the docking station thing etc? Ive heard it has bugs in its fpga core but that can be fixed.
if your interested in chameleon I'd probably wait for fpga-arcard from mike instead...
