I too have similar problems and I am now in the focus stage of collecting.. I know I can't have every last LE that is on the market. So I have made a few very tuff choices
1. Collect what I like at the $5 LE's
2. Collect all of the $5 Greektown LE's
3. Collect OBS Nevada and Atlantic City house chips
4. Trade for any $1 and fractional house chip
5. Collect, harvest and trade for roulettes
6. Collect any Foriegn chips offered in trade
7. always have several chips on my trader page
