We've had fantastic results from the new BioRad HydroTech pump.  The one
downside is that it is probably too new a product to accurately assess
long-term reliability.  Still, we've been putting it through almost daily
usage (and often overnight runs) for several months now with no problems. 
Also, there is no oil or diaphragm to replace with this pump, just water,
so it's not as much of a pain in the neck as other pumps.

Hope this helps,
