Ed,
My 8x10 Ritter is from the inital batch. I purchased it after owning/using a Ritter 7x17 for a year or two. The camera is an absolute joy to work with. I also own both a Zone VI 8x10 and a Wisner 8x10. Both collect dust because the Ritter sees all the action. I would echo Mike Castles comments. My 8x10 lens kit includes a 240 fuji, 305 G Claron, 355 G Claron, 450 Nikon M and a 600 Fuji C. I list the lenses to let you know that I have NOT put a 27lb beast on the front standard, then racked it out to 33 inches for some close-up work

The camera would likely handle that load, but I haven't put mine to that torture test.
About the only difference working with the Ritter vs the heavier cameras is that, once set up and focused you MUST lock the Ritter down. With my Zone VI and/or Wisner, I could focus and just slightly tighten the camera down. Due to the light weight of the Ritter, the camera would exhibit wind induced vibrations if not properly locked down. Once locked down, the camera operated as expected. A slight change in my work habits, but a small price to pay for shaving off all that weight.
Ed,
Contact Richard to see if he has a camera owner in your area. I have let Richard know that if anyone in the Richmond, VA area wanted to test drive a camera, I would be happy to let them demo mine. Perhaps a kind soul in your area can help you out. And don't forget, if you would like to customize your camera (as Mike C. did) Richard is the guy to work with. I already had 4x5 and 5x7 reducing backs for my Zone VI and requested that Richard build my back so I could use the same reducing backs. Saved me a few hundred $, by not having to have new reducing backs made. On the front standard, I already had my lenses mounted on Zone VI boards, so Richard built my camera to take the Zone VI boards vs the standard configuration, which I believe, takes Sinar boards. Again saving me $$ and time since I could keep my lenses mounted on boards that cold be used with either the Ritter or Zone VI cameras.
Good luck in your quest,
