Nathan, Polaroid conversions are expensive but you can pick up a 4x5 Speed or Crown Graphic pretty reasonable. I paid $400,00 for my clean late model Crown Graphic with 135mm Schneider Zenar lens and some Toyo film holders. You can find them for less money depending upon age and condition.

I too once thought large format was expensive and unobtainable.
