It like getting into the pool... Just jump in!!! I got 600+ stamps from eBay for $5, got at least $100 worth of enjoyment out of the sorting, pricing and selecting the stamps for my first stamp pen; even got a couple stamps that I resold for $15 each! Will be honest, first couple tries didn't turn out to 100% of my satisfaction, but the QA department (wife) gave em 2 thumbs up!!
