Another vote for the D-II here.
I got mine for free from a very nice man who offered a D-II, with no lenses but the cone for doing 4x5, flat lensboard.... 4x5 carrier, 4 6x6 carriers and 35mm carrier plus an old, Time-O-Lite 'type P-49' timer and GraLab Model 168 timer, and a bunch of other things.. Very nice of him!
Oh, It came equipped with an aritsto v54 head as well as coming with the original condensor unit with all of the lenses..
I paired it up with a similarly classic looking Vivitar-LU 50mm enlarging lens and Companon-S 80mm,.... I've yet to find a 'real' enlarging lens for 4x5 but using my old Schnieder Symmar 150mm seems to suit me well right now!
I can throw in a side vote for the Elwood 8x10, what a beast that thing is! Ive used one a few times and it is quite the spectacle to need to climb on a step ladder to focus the thing with the big huge battleship like controls..
