I bought a package deal from a local music store that was going out of business a few years back. I paid $500 for about $5,500 or more worth of gear (if I'd pieced it out and sold it), that the store owner had in his garage (he was retiring and just wanted everything gone ASAP - right place right time for me). It was all the equipment from a complete small scale sound reinforcement business (minus the truck) including a full PA w/monitoring system, 2 rackmounted outboard setups, rackmounted power amps, rackmounted wireless setups, all with their wheeled racks, 30 or so mics (some high end good for recording, and some good quality stage mics like 58's and 57's, and some specialty mics like those you hang for mic'ing a choir/orchestra and two boundary mic systems), field replacement parts, electronics/wiring and tools, cases for everything, stands (including 3 hvy dty atlas recording mic boom stands on wheels) and 4 tubs of misc cables. Some of the stuff was what you might call dated, but it was all in excellent condition and serves me well to this day.
I still have my B2 and 122 leslie my old singer from the 70's gave me back then. FREE!
The drummer from my old Reggae band gave me a Juno-60 that he said was non-working. I replaced the battery and reloaded the original soundset and it was good to go. Also FREE!
Nobody told me there'd be days like these...
