If my more modern L1200 is anything to go by, it IS quite big. My L1200 probably weighs in at some 25-35kg, but I don't know exactly.

It has a base plate of 65x65 cm, and a column height of about 1.2 meters. May not sound much, but if you see it standing on a table top...

But it is one hell of an enlarger!

If you do manage to lay your hands on a L1200, you might be better of, since these were produced until Durst quit altogether with enlargers, meaning spare parts are more easily obtained.
