Rio hyper flow pumps reviewed

[outtafocus]

Has any one had any experience with the Rio line of hyper flow return pumps?
I tried a Mag7 as a return pump but it proved to be too weak. So my next purchase would have been a Mag9.5, but I was told about these newer Rios.
The one I have my eye on is the Rio 17hf or maybe a 20hf. They have very good flow, 840gph and 990gph @ 4ft respectively. Claim to be very low heat and run almost silent.

What are your opinions? Any other suggestions for similar flow rated pumps from other manufactures? (available in Calgary)

Thanks, Leighton.
