Seeking information for aquiring a 4x5 slide projector

Hello,

I live in Oregon, United States, and am hoping to obtain a projector for showing 4x5 LF, and possibly 645, 670, and 690 MF slide film.

I understand some of my options are the following:

Beseler Slide King
Buhl AP-4
Liesegang Avanti II
Noblux 4 x 5

I have a few questions,

Does anyone here have experience with these, or other 4x5 capable projectors?
What lenses would be required to use these projectors in a home environment, possibly in a 2 car garage?
Where could I buy replacement slide mounts, slide plates, slide carrier, or materials and instructions to make my own?
Where could I buy replacement lamp bulbs?

I'm not afraid to get my hands dirty, just trying to get all the information I can to make more informed decisions.

Thank you for your time
