Ellis, the only tripod head I have had is the Manfrotto/ Bogen #410 Mini-geared head. Out of curiosity, in what sense is it not ideal?
This is of course a subjective view. I hated the manfrotto QR system and after a year or two. Also it really isn't designed to hold a large relatively heavy heavy monorail camera especially if you are using long lenses. It is fine for field cameras.
If rainer doesn't mind not having lateral tilt I think the best head for a view camera at a reasonable price will be either a Sinar Pan Tilt head (if you don't mind not having lateral tilt or the versatility of a ball head -this is the best tripod head I've used) or a Linhof double tilt pan head. I've never owned the latter but it is supposedly terrific. I'd look for used models on eBay if you don't have the budget for a new one.
