Casio RZ-1-tom 1 does not make a sound but triggers. Other than that the unit works perfectly. Tom could/should be easily fixable.
Yamaha Tx81z
Looking for:
small-ish synths, drum machines, samplers, delay pedals. Battery powered is good also.

Casio CZ-101
Roland tr-606
Yamaha Ry-30 or yamaha rm50
Korg 707
Any decent delays.....
