I use a Durst M601 for 6x6, and it can also do 35mm. It is quite small and very solid. I use Ilford Multigrade filters in the holder that fits under the lens. The Durst M670 and M605 are also very good. These enlargers are more likely to be available in Europe. LPL, Kaiser and Meopta are also popular in Europe. I
have only tried the Meopta Magnifax IV and found it to be quite good, although I personally preferred the Durst equipment. Alex
