There are some deals to be had on the less well known banquet cameras. Check places like
www.mpex.com and
www.lensandrepro.com to see what you can find.
I paid around $550 for my American Optical folding 11x14" camera recently. It's generally in working order with a new bellows that alone must have cost around $400, so I thought it would be a good risk at that price. The "new" bellows, though has a couple of loose ribs (but at least no leaks) that I should fix and some small cracks in the bed that need repairing, but for the price, it wasn't too bad, and the camera is usable in the meantime. I have four lenses from my 8x10" kit to cover the format, and it was easy to adapt the lensboard frame (using a Dremel with a router table attachment) to use the lensboards from my 8x10" camera, and I've got an adequate tripod, so that takes care of a big portion of the expense for the new format. It has a double-extension bellows, reversible back, front axis tilt and rise/fall, and rear base tilt and geared swing. The rear standard slides forward for use with wide lenses, and it's light enough to take out of the house.
I'm still shopping around for filmholders. The best price on new Lisco/Fidelity holders seems to be at Calumet (better than B&H!). If you do look at one of these more obscure brands, be sure that they come with holders or that they will work with modern holders, because some of the older ones may use non-standard holders, and you will pay a fortune for custom holders (go to
www.filmholders.com, though, if you need them). Fortunately, this camera was used by a working photographer (who had a beautiful new Lotus 20x24 in his studio, by the way), who confirmed that it worked with modern holders.
