Wow:
I saw a very nice C-64 in my local Thrift store (wasn't very yellowed, with all docs and such for $25.
This is 4 months back, so not sure if it is still there or not, but if I can turn around and sell them for that kind of cash, maybe I will go buy it :-D
Personally, I have no real interest in the C-64s, but they were pretty cool at the time :-)
I wish those sellers good luck.
I have stopped using E-Bay permanently as a seller or a buyer because I feel that there are too many people out to take other people. (Not saying that these sellers are in that category, because the rule of capitalism is "What the market will bear".) But I certainly even offer up the starting bid when I seem to be able to find rather nice looking and functioning C-64s all over the place for $5 -$20.
Anyhow, maybe someone feels for their 64 like many of us feel for our Amiga and may be nostalgic enough to spend the money :-)
