That is so funny Scottc, we're in exactly the same boat. Almost the same looking chip set as well.
I've been faced with the same decision, but I'm incredibly stubborn. I've taken so much time and effort to build up the set I have that it would seem like a defeat to sell them off, even at a profit. So yeah....I guess it's Crystal Meth here.
I personally could use a few more of the low denoms, but really only need a few 25s and 100s, which would cost me....ohhh.....$200?!!! Absolutely insane.
I've thought about buying up a large set, filling out my set and then selling the rest off in small lots. I've done the math, and even at low estimates I'd make a good chunk of cash in addition to the chips I keep. Problem is, I can not drop $1k on poker chips and still live with myself, even if I plan to make it back.' I also don't want to break up a difficult to build set while driving up prices further for people like...well...us.
I've also thought about doing the same thing as above, but finding a partner to split the initial cost and chips with. Only thing I know for sure is that I'll keep hitting that Ebay search a few times daily
