Wall mount - no I'm in the bathroom on a cart for now.
Lens - looking for a new lens already. I will look into 105mm ones
LPL - its an idea. I've used the regular run-of-the-mill Saunders easels. They are ok. The ones I used were in a school lab, which might have something to do with it, but they were just kind of ok - not straight blades, etc.
