Dear Mike, strange - I just filed a repair job with labcrew for our old ÄKTA Prime. A technician was in house (for other reasons) when it stopped working and he was confident that he can replace our pump (rotary unit, as he called it)... Well let's hope he really does... On the other hand, I had also very bad experience with GE technicians in London, but not yet here in Cologne, Germany. Potentially, it depends on your local service? Regarding Paul Smith's message, I totally agree. A real competitor is needed. I haven't seen anything, which is nearly as good and versatile as the ÄKTA line (which doesn't mean they couldn't bee imporved!). Especially, if you are in Science and not in a kind of production facility. The small Bio-Rad Econo system (about the same price tag as the ÄKTAPrime AFAIK), which we use here in the student course, is not nearly as sophisticated as a Prime...
