Looking for some advice from those of you with experience in such matters.

I've got a great techy idea involving an enlarger and some electronic bits that I think could be pretty cool. I love the idea of taking classic methods and introducing some tech to them (in the same vane as the open-source f-stop timer and such). Assuming I can get this to work out, I'll probably open-source the hardware and software associated with it.

That being said. I need an enlarger. Requirements are that it has to be easily modifiable (the light source must be easily removable/replaceable, etc), accept at least 6x6 negatives, and preferably be somewhat compact (probably no 4x5 behemoths).

Any help would be much appreciated!
