The equivalent to the eheim 1260 is the Ocean Runner 2500. It is only 35 Watts and is really quiet. I don't know about the longevity of the OR pumps (eheims have a great track record for dependability, etc) and I've only had my OR 2500 for a few days, but it is also only $43 from fosters and smith compaired to $119 for the eheim.
I too have heard about reliability problems with the Quiet One pumps in that they often fail to come on after a shut down/power outage. I haven't heard the same RE the OR pumps, but I also don't think many people run the OR pumps so there isn't as much experience with them out there.
Based on my limited experience with the OR 2500, I'd suggest the OR pump over the quiet one.
