Been real lucky (or just VERY careful before purchase!) so far... Just keepers;

K2500S w/KDFX - A little long in the tooth now, but it still does stuff nothing else can, and as a master controller, if your twisted mind can think of ANY whacked out routing and controller assignments, it can do it.

DX7 w/Grey Matter expansion - 'nuff said!

G1000 - over eight years of trouble-free daily (and nightly!) usage. God, I miss the Chord Sequencer! (only keyboard I've let go!)

G70 - Who cares about the weight?! If you want to play the best FEELING keyboard out there, this is it. The B3 is flawed (in comparison to an XK-1), but still the best in an arranger (that's what we play, after all!), but the piano and drums have no equal. Just give me back my Chord Sequencer!

Yamaha YSL-643 Trombone - bought it in '74, played every day since... Now THAT's value for money! A 'keeper' 'til I die.

How many of these 'keepers' do we still have?? All but the G1000 for me (and a friend has mine as a spare, so I can always get it back if I HAVE to!)...
