it depends what i am enlarging to be honest ...
durst m601 ( >6x6 ); omega d3v-m/c ( <6x6-4x5 );
and a omega e4 ( <4x5 - 5x7 )
the durst is condenser, the omegas are both condenser + cold light ..
these days i must admit i contact print more than enlarge .. but i can't bear to get rid of the 3 magi
