Lomo's Instant Back + for Diana

I don't have a Diana but I've been know to do some pretty clever tricks with a Holga and have a couple of the Multi shot bad boys. However, this is a whole new, new. With the recent sad death of the traditional Polaroid this is a just as expensive if not more so option for drunk parties. But it seems like you do have more options like double exposrue...

Also be prepared for plenty of confusion at the Lomo website. There a lot of options, editions, packages, discounts for bulk etc. It looks like the basic camera is around $95 and the Instant Back + is about another hondo. If you buy like 10 packs of film (10 pics each) then you can get them for about $10 a piece. But if you buy all the shit together in a kit then it's only like $XX.XX. I couldn't really figure it out but i still want one.
