I suggest that, if you only are printing enlargements, from 35mm or smaller, you look at eBay for a Leica/Leitz Valloy II b&w. It very well might need rewiring, a five minute, straight forward job and the baseboard may need replacing but as long as it has its film holder, and a Leica extension tube for mounting a m39 lens, it's condenser, in-scratched or chipped, and hopefully a bronze spacer that tightly fits the bottom of the condenser, which is quite small, it should give beautiful prints and is more than enough to contact print up to 4 x 5 inch negatives.
The helical focusing of these enlargers make them super nice for a small print size range, and allows critical focusing some typical enlargers just can no match.
Otherwise, an Omega B66 is a good second choice.
Both will easily fit into a suit case for a traveling darkroom.
Good luck,
Eli
PS; you should be able to find a complete First M600, a great little enlarger that will do medium format like 6cm x 6cm, 6 cm x 7cm, ect.
It breaks down in a snap and goes back up with ease, just make sure all is squared up.
Do no let the eBay "searches" throw you off, these high prices they show off, are rarely close to what the real working kit costs, so do no give up and accept less quality kit, just to have it done, just look a little longer, as the first enlarger you buy should but be part of a permanent darkroom ability.
Godspeed to you and All.
