Welcome to your large format journey, you are really going to enjoy it! Most people find the proper camera for them after they've used them for a while. So I will give you my thoughts and history with my cameras:
1) I started out with a super graphic because it was cheap and portable. I shoot mostly landscape and scenic subjects so it seemed the right tool for the job. It had very nice front movements and could handle a decent variery of lenses. You don't need that much movement at all for landscape specific work, unless you want to start playing around with perspective in which the back movements are important.
2) I moved on to a Cambo 4x5 monorail which I backpack into the field with a Lowepro Super Trekker. I find that my large format kit is lighter than my digital kit because I have less lenses and accessories for it. I got the monorail for a song and absolutely love the amount of control and higher quality of workmanship with the camera. It takes less than a minute to get the front and rear standards out of the backpack and put them on the rail.
3) I recently purchased a Busch Pressman for that ultra-light 4x5 folding camera because I also got it for a song. I still use the Cambo 4x5 monorail 99% of the time.
4) I also recently purchased an 8x10 Cambo monorail. I work out of the car with it because it is so bulky (although again, lighter kit or equal to my 4x5 kit). I also got it for a song.
Bottom line is that you won't be disappointed with any 4x5 camera you get. If you are used to backpacking and carrying weight, you can get away with most monorails. Sometimes the extra movements are great, and the while you can get folding cameras with full front and back movements, you're probably going to pay a lot more.
