Shen Hao should certainly be on a list. The TZ45-II is the simpler and lighter one but still with plenty of movements. They are a joy to use and have a modern look and feel compared to older field camera's. Forty years ago I started landscape photography with a Sinar Norma monorail and would never ever go back to that type of camera. A field camera is much lighter, quick and easy to set up, packs up much smaller, and generally has as many movements as you are ever likely to need. I think however that given the price of film a light meter and a cable release are just as essential as a lens and darkslides. And for darkslides Ebay is a good source. Look for clean darkslides that haven't been bashed about, Fidelity Elite are good and easy to find, but Toyo I think are just that bit better.
Lens boards are easy to buy on Ebay, the Chinese do very cheap but well made boards, and the Shen Hao takes the standard Linhof, Wista, (etc) size board so you have those to choose from as well. Given this is new to you and you will be on a learning curve I'd suggest a box of 50 sheets of Foma 100 (despite its weird reciprocity curve) which generally works out less than half the price of FP4. It is still nice film.
