I picked one up a while back, and it worked fine. If it was used semi regularly and not sitting idle, but not overused/overdriven to the point where it gets hot the life of the caps seems to be greater as I've found. I've got a very very old Concord Mk-10 probably older than this one, using tranny coupled outputs and it works just fine, I've had it hooked up to my computer for years. IIRC I paid the standard $8.98 for it and wouldn't really spend much more. Just something different to try.
