All of these can work. The Dursts and De Vere's followed by the Saunders are nicer, though, than the Omegas and Beselers. Given the low cost of all of these, I recommend spending some time and getting one of the better ones. Mind you, you'll have to pay more attention that all of the accessories are there, as they can be hard to find. The great thing about, for example, a De Vere is that it's very easy to align all of the stages. I have three De Vere enlargers, and I love them.
