$350 is way to high IMO - but if the guy can get it...
I remember it wasn't long ago NOS A500's were fetching $80-$100 on ePay here in the States. Wasn't long ago at all.... maybe early to mid 2000's. They *are* still out there and crop up from time to time. Same with A1200's. And as others have mentioned, finding some NOS A1000's... now that would be a treat worthy of the $350 tag :-)
