You are probably familiar with this already, but just in case, here is the link to KHB's excellent resource on Omega enlargers. Just click on "Discontinued Enlargers" on the left: http://www.khbphotografix.com/omega/index.html

And another great resource that you probably already have seen - Harry Taylor's Classic Enlargers site: http://www.classic-enlargers.com/

Harry is very generous with his contributions on the Help Forum (and KHB are known to chime in there as well).
