Both my trusty (until now!) SD-35's are exhibiting classic "about to fail" disk drive faults. ROLAND tell me they CAN order new replacement drives for the units. They better have - as they've taken my money and promised delivery. I have used these units three/four nights aweek for ten years and apart from keyswitches failing (they're really flimsy but they give good warning)the units have kept me in good work. I too tried the Itialian job. The GM sound source misses (of course0 the expanded sounds on GS I usually use BUT the MAIN problem with it was a distinct lack of COMPLETELY reliable key action - sometimes meaning multiple (often lots)of stabs to start songs. Occassionally toital hang-ups. Harldy professional - never mind the sound (though I believe there is a GS version out now) Bet it has the same hardware faults/build spec.
