Thanks for the lens suggestions. It really does seem like a huge undertaking! However, I remind myself that I am young (20) and this is something I've been wanting to try for quite a long time. I'll work through it one step at a time.

On the topic of lenses, I want to start developing 35's before going into the 4x5. Do you have any recommendations for good quality lenses that would fit the 39mm thread lensboard on the 4550 xlg? A specific lens would be awesome, but if not, brand, or features to look for would be great as well.
