Just an observation but for me, in the transition from small format to larger format, the biggest issue was the upgrade of the darkroom. My biggest cost factors were in the 4x5 enlarger, the enlarging lens, figuring out how to develop the negatives etc. The bulk of the investment in the camera side comes in the lenses, and one nice thing about large format is that the lenses can be used across different camera platforms - invest in a good lens, and put it on a graphlex first - if you find that you want more movements, get a monorail and use the same lens, or if you are hiking and want less weight, a Tachihara folder may be the answer - again, you use the same lens.
Check out Large Format Photography Forum. Their home page has a wealth of information about large format and it's free! It has really helped me out. Also check out "Using the View Camera" by Steve Simmons. Steve's book is available on Amazon and has also taught me a few things.
Membership is free at Large Format Photography Forum and after I believe 30 days you can access the for sale section.
I'm a member and I recognize a lot of the APUG members here also being members.
The forum at the Large Format Photo site is http://www.largeformatphotography.info/forum/
The top level domain is .info, not .com as most folks would expect.
I'm a member there also. Great group.
graywolf: Thanks. Well, I'm taking a Large Format class this semester so I'll probably spend a few weeks learning stuff there before I shell out the $ for the camera....
