Stay on ebay. As a matter of fact you can get ebay to email you everytime a car gets listed that meets your requirements. That's what I did when I was looking for mine. Saves the time of looking. Also stay on forums like ls1tech and others because cars are always being listed on there too. If you're willing to spend $10k you can have a very nice one with mods and all! Seen them myself.
Personally I'd take stock over modded so I can do everything myself, but since now I know what's what, I wouldn't mind taking a modded car after a thorough looking over and really good test drive
