Best Pump for 810 - 900 gph @ 4'

[foulbrew]

Now that the lighting has been decided, I'm on to the pump. I'm looking for the best external pump for my new 92 gal corner. I seen to remember the optimal turnover being 7 to 12 times volume and am thinking 810 to 900 should do the trick. Is this correct?
I'm considering :
Dolphin DP-900 rated at 900
Amp Master 3000
Aqua Sea 2100
Little Giant 4MDQX-SC
Any testimonials would be appreciated for any of the vendors, including any not listed. What do you guys think.

JUST PUT A MAG 9 IN MY SUMP/REFUGE WORKS GREAT! LOOK AROUND ON THE NET I PAID 70$ FOR MINE

It seems the Mags are not recommended for external use... is this accurate?
I've been getting alot of positive feedback (on another board) on the AmpMaster 3000 as well. Does anybody here use it?

I have a Hagen 901 used it 10 minutes too much for my tank. Let me know if your interested.

I run the Little Giant 4MDQX-SC on my 150 gallon FOWLR, and it has been great for me. I have it screwed into the base of my stand, with an old mousepad between the base of the pump and the wood. It is much quieter than the Rio 2500 I was using prior to the upgrade.

Little Giant for external use...mag 12 (for 900 GPH at 4' head) if used submersed.

So is it better to get submerged or external?

I have a mag 700 used external..........yeah it stays a little warm, but besides that, I have had no problems at all with it!
