The ones I just bought, after looking around and buying a test sample of the Soprano as well as the Nexgens were the Neophyte line from BuyPokerChips.

They cost just over .25 a chip - but feel much nicer than the Nexgens. They feel about the same as the Soprano line, to my fingers anyway. I like the look of them - but they also come with labels preinstalled. For me that was a good thing - I understand for others it's not. The lablels have a laquor over them, so they don't scratch at all. I've played through a few (3?) different evening games now with them and am quite happy.
