WTB [FR, EU] HP 66XX series power supply, or a GPIB/RS232/USB capable one

[Lemonizer]

Hello !

I'm looking for a power supply with at least 2 outputs (4 like the 6629 would be a dream) hp power supply, they are cheap in the US but hard to find in europe, at a decent price... maybe one of you fellas got one for sale ? 50V would be nice, if not, just tell me what you have !
And if you have any other GPIB/RS232/whatever capable power supply for sale that meets the requirements (even if its one output, im really desperate at that point anyway) just tell me please ! 

Thanks a lot,

Robin
