I bought a CV for $200 on theaterorgans.com, but I gutted it for the pedals, so I could make midi-pedals for my CX3....not to mention I couldn't ship a full organ here to Korea.
You can get some good deals out there, if you know where to look. I'd look in Ebay and theaterorgans.com or your local newspaper. If you pay more than $1500 for an A100 that's not spic-n-span then somethings wrong, in my book.
