I have little to add, except to assure you that the advice you've been given above is first-rate. My thoughts echo RichMahogany's.
Oh, I would add this, regarding expense - of both time and money... if you go with a custom set from CPC, be prepared to potentially spend more of each, for two reasons:
1. You'll be able to choose complex spot patterns that come at a higher cost, and having the freedom to choose colors and patterns means time spent.
2. You'll need to provide some sort of art or theme for the inlays, which usually entails hiring a graphic artist - there are several excellent ones here on the fora.
3. Customs from CPC, like anything hand-made on specialized and rare equipment, can take months to be produced, depending on which molds are currently in rotation for production runs.
Hmmm, last thought (I was wrong, I'm a windbag and always have something to add)...
You might also consider getting samples of the Key West chips. The Key West line of chips, which you can get from the fantasy Key West Resort/Casino, are produced by CPC (or, if old stock, were produced by ASM on equipment subsequently sold to CPC). They are made with a simple spot design to keep the cost per chip down, but they are pre-stocked and you can buy samples or playable sets on demand. The nice thing is that you can also plan on buying more from them in the future to expand your set, and they offer like-themed accessories.
