Which Return Pump for basement sump?

[Carandiru]

I'm in the process of plumbing a basement sump and I've done a lot of looking around for a decent return pump.
Key things I'm looking for are:

• Energy Effiecent
• At Least 11ft of Head Pressure
• More GPH the better
• Not too expensive

I've narrowed my selection down to:

REEFLO BLOWHOLE BH1100 http://www.incredibleaquarium.com/in...oducts_id=2281
$174.99

WATER BLASTER HY 7000

$249.99

RLSS Controllable Waveline DC 10000 Pump

$329.00 + 20.00 shipping

I really like the Waveline DC due to it's efficiency and being not much more than the waterblaster hy 7000 you get a lot more GPH. The only thing is the Coravue Waterblaster comes with a 3 year warranty vs only 1 year for the Waveline DC. The blowhole is energy efficient too but external only.

So what do you guys think? I've had a look at all different types of pumps and these three seem to be the most energy efficient of all of them - or am I missing some? Really don't want to spend more than $350.00 on a return pump as there is other stuff I would like to budget for and buy for the whole setup.
