[2F/2F]

It sounds like a good kit for an OK price, but it is not the first thing I would buy if I was just thinking about 4x5, as you stated you are. I'd get something cheaper and more basic, like a modern (black) Calumet, Omega, or Toyo monorail with a lens or two. They are everywhere in good shape for peanuts, and are full-featured view cameras. "I want to try 4x5; here is $1,000 for everything I need" is not a good approach IMHO. In other words, to get into the pool without knowing how to swim, I'd not jump into the deep end straight away, but would come down the steps on the shallow end one by one. YMMV, but that is the way I see it.
