Rich,

Just looking at it from the 4x5 standpoint right now, and you would be amazed at how low the material costs are, once I was set up, I could bring a 4x5 to market for a very reasonable cost, and I have 90% of the tools right now to do it...bellows are not that hard to make, I have done quite a few of them, in fact I have now taught my wife the process and she is better at it, then I am, she can do a complete bellows in a very short time, they can become expensive, depending on the material you use, but even with using cordovan leather, I can do them quite inexpensivly..

Just some thoughts, send me a note and I can eleaborate a bit more.
