I think Spreadshirt is a pretty good place.

Not to derail or anything but does anyone know of any other sites where I could sell shorts? I like MySoti's look but it's not too popular and slightly more expensive and limited than Spreadshirt but I really don't like spreadshirt's layout (for the free account). I don't like Zazzle and Cafepress either.

i havent heard good things about cafepress, at least about ther tees anyway. you can print on a lot more stuff with them though

Try this site

http://www.customink.com/

I don't know about CHEAPEST - but mysoti.com definitely does a good job
