Depends on the continent and the pedal set. I offered $80 on a T12 with princess pedals (52" long) and a gyro cabinet, was turned down she wanted $150, I don't believe she has had another buyer, she keeps emailing jokes and other trash. I changed my mind about wanting it, I find after one lesson on a pipe organ I am just big enough to reach both sides of AGO pedals- so I'm holding out for a Baldwin with AGO pedals. DW15---- listed a T12 princess pedal organ at a church in Indi, has been talking about them wanting it gone for 6 months, the princess pedals are a real deal killer. Besides the limited palette of tones. Repairable simple organs if they just had AGO pedals (56" long) they would be useful for practicing.
Leslies with the full sized cabinet, even non working, rarely go below $500 here. Not the sort of thing that shows up on Craigslist very often.
