I'd like to see this "Chicago" set from TommyTheCat (hey, the Pink Floyd Crystal Parks and the Rush set are pretty nice). I like Harry's "C U Next Tuesday" set in the Flamingo font, too. However, the 16th edition Dunes are my favorite so far.
My fav poker chip set is the Tiki Kings set. The unusual patterns and the cute tikis are really nice to look at.
Runner up is the Nevada Jack Saloon set. I like the feel of the surface - and it has a skull on it.
