I agree with Ron Marshall, the learning curve isn't all that steep, but managing the equipment takes some getting used to. If what you're contemplating dosen't require perspective control (movements) a Crown Graphic should work out fine. If OTOH you're considering timed exposures or movements, something like a Gowland Pocket View would IMHO make for delightful travelling companion. Both these are very lightwieght so they won't require a heavy tripod---the Crown won't really even need a tripod. Conversely you can get something like a Technika and have the best of both worlds (but wiegh more!) Another item to consider is using grafmatics rather than conventional filim holders.
Perhaps one approach is to study LF 'togs whose work is similar to your vision, learn which LF camera & gear they shoot with, why and how.
Good luck & enjoy the wine!
