Best place to fig hunt in Las Vegas and Los Angeles?

I'll be up in both places at the beginning of March, wondering if either have any particularly good spot to do some figure hunting.  Would love to find some early-mid 2000s stuff, Classics etc.  I'm also really looking for a WWF Jakks Attitude Era Championship. 

Anyways, any thoughts on stores to hit up with these and other cool vintage/retro toys and collectibles would be appreciated!
