Yeah I use ebay for small parts. One thing I don't like about ebay with big things is people say only pickup which makes it hard. The other people say they want a lot of money to ship it. I try to stay away from ebay with big purchases just because you don't get to see the item before buying it. If you don't get to see it, the seller could lie about the object. You just never know.
Craigslist on the other hand i love. I sell alot on craigslist and also buy alot. I like it better because you can go see it before you buy it. If you go look at it, and it's not the way the seller described it, you just say I don't want it. Thanks. Also you can offer under what they are asking. With ebay,you pay their price or you try and bid to get a lower price.
Hope this helps.
