Not really. Amiga hardware is hard to come by here and it is stupidly expensive, on eBay especially. And, even if you find a seller that isn't listing it on eBay, everyone checks eBay prices first, and assumes that's what they can sell theirs for too, no matter what the condition or working state. I live in one of the southernmost parts of the US, and there is positively NOTHING here. Not even C64s, which were immensely popular locally back in the day -- I knew at least 4 other kids in my neighborhood that had one, met countless others at local "swap meets," and there were tons of BBSes run on 128 or 64 C-Net back then. Forget finding an Amiga here, too.
I think only Europe has a glut of it, and most of those guys hoard it -- it's disgusting to see some of these people with warehouses full of unused commodore stuff, never recapped, and rotting away inside pristine, original boxes, because they have to have bragging rights to having "Europe's largest collection," or some such nonsense. Maybe some of the larger US cities might be more fortunate, but, definitely not my part of the country.
Back to the topic, great find Eric. And, you were fortunate that the 3000 had the GP battery, instead of a Varta. Varta, for some reason, seems to always leak more and cause more damage than the GP batteries...maybe they were of poorer quality.
