I have a Beseler Printmaker 35, and I understand what Bryce is saying about rigidity. I don't think I've experienced the alignment problem, but I've noticed, for example, when I crank the lens to the topmost position, the lensboard angle changes. It's not an issue because nothing would focus there. At least not for the sizes of prints I've been making.
I managed to pick up a Schneider Componon 50mm f/2.8 lens for about $50, I think. It seems to be new, although it wasn't sold as such.
I agree it's important to think about what supplies are needed, and where you'll get them. I paid $75 for a 35mm negative carrier 2 years ago when I first got the enlarger. A couple of months ago, when I acquired a Widelux camera, I went looking for a negative carier for it. It's the same width (vertical measurement, when used in landscape mode) as 35mm of course, but nearly twice the horizontal dimension. I never found a pre-fab carrier for it, but I found another standard 35mm carrier for $8. I'll have to modify it myself.
IMO, there are many bargains in darkroom supplies.
The digital photography "fad" is creating a wonderful buyers market in analog equipment.
