You'll find something eventually, but it may take a while before the right deal pops up. Keep stalking ebay and the forums... heck, a CV64 sold here for $75 a few weeks back. (Man, was I bummed to miss that!)
I've had a few projects (some ongoing) where it has literally taken years to put the system together the way I wanted. It can be a pretty nerve-wracking hobby at times. :lol:
