Hey, just joined the group and despite this being an old conversation, thought I'd join in! I live in Lawrence and if you ever see a guy carrying around some old Canon's or using a 4x5" monorail... that's probably me. Just built a darkroom in my house as well.
Unfortunately, as you probably know, Image Works has closed down. Very sad indeed.... but at least there's Kansas City. Overland Photo Supply has a lot of great stuff (4x5, darkroom galore, used lenses, etc.) and Express Photo (Brookside) is a great lab, though not much for sale. The guy there, Steve, seems to be quite the darkroom guru and very nice to boot. There's also a lab near Overland photo supply, near the Home Depot I believe (but can't remember the name). Also, here's a little film shop near Lulu's Thai Noodles in downtown KC that has some paper, some film, TONS OF CHEAP FILTERS/LENS CAPS and a few vintage cameras. IIRC, there are a handful of Nikon F's in a case.
A must see place in KC is the huge antique store in the River Market area. On the 2nd floor you'll find one of the most mind blowing collections of vintage camera equipment in the Midwest (I feel confident in making this claim!). Tons of really really interesting old stuff, from wooden film holders to crappy polaroids, to Graflex, etc. Amazing.
Anyways, howdy y'all, don't be a stranger
