It depends on how many chips you "need". Are you ordering personal chips just to trade with other chippers? If so, 500 would be way too many in my opinion... and they ain't cheap! Is this the only chip you'll ever do ... or will you be planning another issue in a year or two? I'm doing a new chip right now that will only be distributed (complimentary) to my A.C. New Issue Subscribers later this year.
