My two-cent's worth:
I have a liking for some British enlargers, such as those by MPP (the medium and large format camera people), Gamer (later Gamer-Congreave), Wasp, etc. I bought my 1949-model 5X4 Wasp a few years ago and it was old and a little battered, with missing negative carrier, for A$50; that's US$30-something. I had it dismantled, hand-finished all the parts, paid special attention to parallelism, built a hybrid-type negative carrier with glass on top, got an adapter made to take a superior Componon 150mm lens in lieu of the less capable Wray, with which I produced the finest prints out of 4X5 negatives imaginable, even with the same lens I was having a little difficulty replicating the same quality out of a floor-standing Durst Laborator 35 (maximum 5X7 negative size). The other Wasp enlargers are also just as capable, and are miles ahead of the comparatively common Welsh-made Gnome enlargers; if I could find a Wasp Junior DeLuxe (6X6 format) I would be very very happy indeed!
Many Durst enlargers can be considered classics, of course, I run the darkroom of a photographers group and it is equipped with three Dursts for three different formats, and they are all sterling performers, and would be quite inexpensive to procure nowadays.
I still regret not having acquired a 5X7 MPP enlarger with helicoid focussing about 15 years ago; I was apprehensive because it was in a huge cardboard box in component form, covered in what looked like an inch of dust.
