If you want the opportunity for the best show possible, can the spreadsheet idea. This has been discussed several times (RGP) over the past few years, and I won't rehash the reasons. Last year there was little spreadsheet drama, and both the number of games and quality of game titles was much improved. Many, many games are for sale in both freeplay areas and fleamarket. Do your want lists - post here, or Mr. Pinball, or RGP - but keep the show out of it.
