I'd highly recommend shelling out for some Paulsons, TRK, BCC, and other peoples' customs, based on what you have locally available, and buying many sample sets.
For two reasons:
1. You won't really know what you want in a chip until after you've had some - and, preferably, hosted some games with them. Nearly everyone who went straight to customs would have done things differently. Thinking you know what you like or don't like or would want, long-term, from photos turns out to be deceptive.
2. Most Paulson, TRK, BCC, etc. chips that you buy on the secondary market will retain their value. Once you're sure you know what you want in customs, you can sell them, most likely near their cost. So there's little risk in buying them - you may even make a profit. If you order customs and don't like them, you'll most likely be unable to sell them for more than a small fraction of their cost.
