I've been setting up my own darkroom for a little while now. I used De Vere enlargers at college and I now have a 504 of my own. They really are fantastic, and quite easy to set up. However, if you are a little unsure as to setting up, I'm sure you could just as easliy give the Omega a good clean and sort out it's levels and be ready to go. A final thought. I'm London based but spend quite a bit of time in NYC, and from looking round the De Vere seems more popular in the UK than over there. Spares and enlargers seem to come up less on ebay US than they do here. Perhaps it would be best to use the Omega just in terms of support.
Not that I've ever heard of De Vere's breaking! They really are the business!
