You would do well to read Ctein's book Post Exposure or whatever the title is. By light years the best information on enlarging lenses. As far as enlargers go, most I have used/fooled with are a long wy from what they should be. I hahave managed yo make my poor old Beseler so that it is fairly fast and easy to align (in all axes both lens and negative stage) and by the use of masking tape and putty-like stuff get rid of all the light leaks that matter. Otherwise, they all seem pretty much the same (poorly designed and cheaply made) except for a few _ I am guessing - inthe 8 to 10 thousand dollar range. After all, an enlarger is just a projector, and the light source only needs to be very even, which most are. The difference between condensers, diffusion and cold light is vastly exaggerated. It would be very tough to tell a good print made with one source rather than another. Read Ctein,s book and I think you will be enlightened!
Thanks John. Is that the little programmable timer which you can plug onto the wall? I think I have seen it and it's quite cheap.

Yeah, buzzer and glow in the dark numerals are nice features. There are a lot of cheap Gralab timer on eBay but they are all 110V AC, I need 240V

If you have V-Elmar version, you can easily exchange it for Focomat-II (if you are able to find it). You can find more information here: http://leica-users.org/v31/msg11354.html
There is German company which maintains some spare parts and upgrades Focomats:
They also can exchange the lens mounts to accept modern lenses, although it's quite expensive.
Contact them for more information.

Whoa! Thanks palec. The ability to use modern lenses on IIc is great news! The site doesn't state how much it will cost tho. But I still hope I can see a comparison with V-Elmar and Schneider. Yes, Focotar II is very hard to find, it's like a myth. I've seen a great demand on this Focotar II lens since early 90s(from reading old forums), why can't Leica just make it again?

My omega D6 chromega does fine work from 35mm to 4x5, although I had to make /modify a 35mm carrier with a glass top. It is easy to allign and it stays that way.
The D2 also does fine work.
As far as diffusion vs condenser, a neg developed to print on either with #2 paper will look very close. Diffusion does not hide dust on a neg. how could it without obscuring detail? When working with small neg, a condenser will show a little more prominent grain but the effect is so small that you have to have comparison prints side by side. You can not look at one and say it is diffusion or condenser.
Taking one neg and varying the paper contrast does not give the same result. You must optimise the development for the enlarger and then put the prints side by side. Then you will be hard put to see the difference.
All that being said, I use a Focomat Ic for 35mm and the V35 sometimes. For 4x5 usually I pick the D2 over the color head D6. All color is done on the V35 and and Chromega.
It is all in the lens. That is where the money needs to go. Then a well alligned enlarger. The rest is all your skill.
