I'm pulled in two directions, since press cameras (all those Graphics people are recommending) are very suited for portraits and use at the beach (two of the primary uses mentioned by the OP) but at the same time, press cameras are only "sort of" view cameras, since what they gain in portability they lose in terms of movements. If the OP really wants the "LF experience," I tend to suggest something in the direction Ari's post is taking, a monorail, the type of camera which is the most flexible form of view camera. I would suggest something in the Sinar series, either an F2 if you can find one, or a Norma in good condition. The Sinars are a total "system" approach, with loads of components and accessories on the used market, and almost every one interchangeable. You can get extra rail sections and bellows if you want to use really long lenses, a bag bellows for really wide lenses, and even a Sinar shutter if you want to use lenses in barrels. The "F" models and the Norma are the most "field use friendly" of the Sinars, the "P" models are excellent studio cameras, but not designed for field use.
