How about two coins:
1 for purchase and 1 special award coin?
Special award coin>general coin>no coin
The general coin would support the program..... Anyway just a thought......
Does anyone have one? I was looking at a few of the "affordable" ones fron Optishot and P3Pro... Looking for something under 3K (I know that's not much) but if you have any experience with the ones listed above please chime in....
