Hey Ken -
I'm sure you can get them cheaper if you look around, but check out www.gamblersgeneralstore.com

The store is in Vegas and is well worth the trip if you are in town.

They have quite a few different sizes and even shapes depending on what you are looking for. Nice frames (lucite on both sides so you can turn it over and see the reverse), however a couple of things I don't like - the chips move around a little too much in the frame, so as you get them aligned, you need to be careful. Second - take a look at the frame when you get it to orient the holes. You'll see what I mean if you mess it up.
