You can not buy firearms on ebay, only non licensed parts... ie no lowers. gunbroker.com is good, as are some of the others listed. Just make sure you educate yourself before you buy. I have over 20 M1 carbines in my collection which are going to be displayed at our museum after we work out the donation end of it. The beauty of the carbine to me is its versatility, compactness, and durability. Look for non-import (ie no new stamps after they were reimported, as said before, no rebuilds, and basically a piece that is not beat up, and is fully functioning. Another key, especially in the case of Garands, but matchjing serial numbers is key to the value being up there. All in all, it is a great thing to do, the M1-carbine is kickarse!
