Figuered this would be the best place to post this,best place to buy comics

[Doctor Who?]

Can anyone here tell me what the best site is  for buying old comic books online.

I am mainly looking for Marvel and DC stuff I read as a kid in the 90s.

I would really like to find some of the Sonic and Star Trek comics i used to read since my brother and sister seem to be really getting into those two things.

I have checked Ebay but some of those seem over priced with some of the comics going for over $20 apiece.

Any good comic book websites out there with better prices.

Thanks alot

Go to cons...seriously, I have found every comic I wanted there.  Including the entire run of Nightbreed which I lost during the late 90's in a breakup.
