Oh yeah, I nearly forgot, Hasbro Toy Shop is another option too, if you collect Marvel Legends, Star Wars, or Transformers.

I still prefer BBTS, but sometimes they don't offer certain Marvel Legends individually.
For instance, back in '03, I really wanted the Jean Grey figure from the Rocket Raccoon wave, but I didn't want the entire wave. BBTS wasn't offering her individually, so I resorted to HTS for my pre-order, and I had no issues.

I honestly can't recall any other occasions when I've pre-ordered from them, so I don't have enough experience with them to give them a glowing recommendation, but they seem to be a reliable option.
