I was not aware they had gone up so much. When I was last shopping, they were in the $200 to $300 range as a kit with lens, holders, flash, case, etc. Less if beat up. Maybe $350 or $400 for one in a kit that was near mint condition.
I over payed for my Speed at $500 because 1. It was as close to dead mint as I have seen one. 2. It came in a kit with everything. Case, holders, changing bag, lens, etc. It included, in addition to the mounted Graflex three-cell flash, an extra bundle of three Heiland flashes, extra reflectors, a flash extension socket, a pile of synch cables, modeling bulbs, an extra case, and about 500 flashbulbs.
Anything you can do with rear movements you can also do with front shifts as an alternative. I agree that it is less than ideal, and more limited than the aforementioned cameras, which I why I suggested a user example and modifications that allow increased shifts. However, the savings in $$$ might be significant enough to make it a viable option to some.
Not arguing; just explaining my suggestion.
