Mine is an Omega D-II, condenser head.
It's identical to the storied D-2 only with an armstrong head elevator instead of a hand crank.
Works fine, I like it, no complaints and it was extraordinarily inexpensive.
Since it is used only for 4x5 I didn't need a lot of extra stuff.
Used parts are plentiful and can be cheap or expensive, depending of where you buy them.
I think either a D-II or D-2 is a fine machine to learn on.
Many Pros still use them (and Beselers) with excellent results.
Consider getting one and spending your $$ on a quality lens.
