I know of a complete set of Omega D5XL available for sale in Detroit, MI. Including full set of negative carriers from 35mm to 4x5, power supply-timer, spare parts, three El Nikkor lenses 50, 75 and 135. The price is $450. Seller is a professional photographer and he's very kind. He is ready to disasemble, pack and ship the enlarger. I almost bought this set but the shipping cost was way too much so I had to give up.
I'm not sure if it's still available but if you are interested, let me know and I will give you his contact info.
