I would also advise you to get either a Bronica ETR/s/i or a Pentax 645, both are capable, lightweight (for MF) cameras with very good, decently priced lenses.
But don't let anybody talk you out of a TLR! Waist-level finders, no mirror shake so they're dead silent, and they're extremely lightweit. Plus, they can be had very cheaply if you go with a Yashica-Mat or a Minolta Autocord. Even Rolleicords can be had for a decent price.
