I know that you've already found your condenser, but if you ever want to automate your tank-of-an-enlarger, Heiland Electronic makes a version of their Splitgrade automatic light source & exposure system which custom-fits the Durst M700. (http://www.heilandelectronic.de/html...grade_main.htm).
Statement of transparency: I do know Juergen Heiland and consider him a friend. He has bribed me with several beers in the past. But to hell with the naysayers: the Splitgrade is damned good equipment and Yan ought to know about it! To me, it's tantamount to letting him know that Porsche engines fit into a VW Bug! ;o)
