The Linhof Technika's strongest suit, IMO, is hand held use. Other than that, with today's used market, the Sinar beats it dollar for dollar hands down. They are not hard to carry in a backpack, and definitely no problem "on location", when you can roll or carry the camera case from your vehicle to where you are shooting. Aside from the aforementioned hand holdability, they only really give up anything to the Linhof in terms of size and quickness of setup. Weight is about the same. (At just under 6 lbs., my Sinar F-1 sans lenses with a 12 inch rail is actually lighter than either of my Technika IIIs.) The Technika folds into a nice and compact "brick", while the Sinar is kind of gangly in comparison. Thus, it would seem that the Sinar is also more likely to get damaged from being backpacked, though I have had no problems.
I suggest the F-1 or F-2 to start if what you want is a general-purpose camera similar in style to the Cambo you used to use. If it becomes cumbersome for "the field", there are many options for the field. The Technika is only one of them, and perhaps even one of the least preferable when compared to the many wooden field cameras that are available, as well as the other technical/press cameras that the fellow above mentioned. The Super Graphic is my personal favorite of the lot.
