This is an odd question, but I need a computer I can easily buy and resell. Why? Allow me to explain.
About a month ago, I began a computer/video-game restoration business. I would buy up vintage computers and video games from local flea markets ad thrift stores, clean them up, and sell them on Ebay. All was going well, until my best friend caught wind of my idea. With his small, growing knowledge of classic video games, he asked(More like demanded) to partner with me, but I allowed it. We picked up a few video game systems off Ebay, and are in the final stages of restoration. However, he is only aimed at video games. No matter what I say, he is convinced there is no vintage computer market, and will not chip in any money in the purchase of one. I've tried convincing him to buy a Vic-20, Ti-99/4a, and a PET, but he has "Never heard of these" and doesn't want to buy them.
Basically, to reclaim my business and manhood, I need a cheap, easy computer I can buy and resell to prove we can make money off them. I was thinking the Sinclair 1000 or a Commodore 64, but they usually sell at un-flippable prices on Ebay. Also, the local flea markets have run dry, with nothing really left besides destroyed IBM's. Any ideas?
