gsfreak I know how you feel, I'm 14 and I just got a CRT and had to pay for it my self, but luckily I got somthings used for a good price.

If you don't want to spend alot then take a look into STS engines http://www.projectzen.net/index.html (if some of his links don't work then e-mail him, He spends most of his time with orders and not to much time with his site) and heres another place http://stsmicroengines.com/index.php?main_page=index

I hace two of them, and I don't thank I'm ever going to buy anything else, but I might maybe, but not anytime soon.
