Cheapest Polaroid 55 setup.

I really would like to try polaroid 55 before all of the film is completely dried up. I need to know what is the cheapest polaroid 55 setup? Instax doesn't seem feasible to shoot 4x5 film, so should I try to modify a disposable? Are there any cheap 4x5 cameras out there for less than $100? Thanks for the advice.

How about a 4x5 pinhole camera? Toss in a Polaroid holder and you're good to go. You could probably do the whole outfit for around 100 bucks.
