The last of the New55 production is for sale by one of the owners of New55: Dead Link Removed
All of the Fuji FP100b45, FP500b45, FP3000b45 and FP100c45 is long gone and goes for crazy prices on auction sites. Same for the Polaroid 4x5 pack and sheet film. Your best bet, if you really want to take a few shots, is to look for a reasonably priced box of Polaroid 52 or 54 on Ebay. If you're patient you might get a box of 20 sheets for $40-$50, and if you're lucky that box will actually work. If the expiration is before 2006 I wouldn't bother. The latest expiration dates were 2009.
