Well, if you've never used a LF camera before, one of the (IMHO) best cameras to start with is a Sinar. The fact that there are precise scales for almost everything will help you a lot in the learning process.
One of the things which is special with almost all LF cameras is the ability to tilt and swing the lens plane and/or the film plane. With a Sinar it's quite easy to use these scales and gadgets to get the tilts and swings right on the first try. I.e. this will speed up the learning process with better end results from the very start.
But as you havn't bought a LF camera yet, all the technicalities can wait. There will be a lot of questions down the line. Anyhow, whenever you decide to take the leap: Welcome to the world of LF photography!
