We have been using MacScience M06XHF22-H, which is also distributed 
by Siemens in Europe, for about a year.  It is compact and good for 
protein work. We use Cu with double focusing mirror from MacScience 
and normally we operate it at 50kV 90mA.  The filament lifetime was 
in average about 1000 hours.  Filament change or anode replacement
is very simple.  As its maximum power is 6kW, our chiller is also
small Neslab HX-200.  When the generator is in 50kV 90mA, the 
electricity comsumption is 200V 30A 3-phase.  If you need more info,
don't hesitate to contact me.
