While a kit sounds like a good idea, I am not sure that it would be all that "cheap." Jim can give us better info, but one of the mayor expenses of the kit would be the bellows. Bellows for 8x20, 7x17, 12x20 etc, are expensive, not because of the materials but for the labor involved in doing them. They have to be folded by hand, no other way about it. So lets imagine an average of $375 for the bellows, add another $375 to $400 for the wood and all the work involved in cutting it etc. You are up to $700 to $800. And you still have no holders.
Jim is now offering holders at $185, but in the past the chepeast holders were made by King and Sam Wang for $395 each. Brubaker and Wisner as well as Lotus charge somewhere in the neighborhood of $600 to $900 for their holders EACH!
So, for a kit you would be looking at at least $1130 and you would still have to put it together. Most likely anybody that would undertake this would sell it for about $1400 to $1500.
This is why James' camera is a great deal, depending on the format you want for a few hundred more you can get a brand new camera with two holders, and it is the reason I auctioned mine so cheap with 3 holders. I had to make it attractive as a starting kit without at the same time loosing my shirt in the deal.
As Jim said, I decided to buy his camera sight unseen for a few reasons. One, I have been the recepient of wonderful support by APUG members who have bought my prints. I beleive in passing around the good karma. Two, I think Jim is doing something which many camera makers are going to say "why didnt I think of that?" Revolutionary ideas deserve support. Third, I have found photographers in general and APUG members in particular to be a pretty honest bunch. I know I wont be screwed by Jim.
On the subject of "feeding" the camera, it really is not that expensive. Sure, film is much more expensive, but you all have to realize that shots appropriate for these formats are not all that frequent. On a typical outing you might see 1 or 2 shots that would be good in ULF as opposed to many more which can be done in 8x10 or 4x5. So you tipically dont use that much film.
So as I see it anyone wanting to get started in ULF has a few options. You can be patient and wait for someone like me who is upgrading and places their old Korona on e bay. You can save a little longer and get a smaller format from Jim, I imagine a 7x17 or an 11x14 would not be but a few hundred dollars more than an E bay auction for a brand new camera with holders. There is always the do it yourself option, but I think that ends up costing more if one factors in the time it takes to make it.
