1) and 2)

Then you will have something like what I have .

Both are good quality. If you now have or in the future will have room for both, you can dedicate the Beseler to 35mm. Or to colour printing. Or as a light source for paper flashing ...

The Beseler is quite a bit smaller. Accessories are reasonably easy to find on eBay for both of them, although I seem to see better prices on eBay for the Beseler. You can even buy new stuff for the Beseler (it is essentially the same as the current model).
