Colorpacks are great. I have two Colorpack IIIs. I love the goofy little "rangefinder" device. It actually works (more or less).
I also just picked up a Big Swinger for $1. It only takes Type 667 (ISO 3000) film, but Fuji makes FP-3000, so it may keep clicking for awhile. It has a crappy meniscus lens, so the pix aren't as "refined" as the Colorpack productions.
