I have a set from TR King and I'm very happy with them. You can buy a sample of their chips and use the cost against a set if you buy from them. Both sites offer chips w/out edge spots for about @ $0.50 each, so a set of 500 would cost about $250. Don't know if that is in your budget, but the chips are worth it. Check out some of the other threads here on this topic. Some people have posted pix of their own home sets and it will give you some idea of what the chips look like.
Good luck.
