Which Return Pump for basement sump?

[Carandiru]

Well that knocks it down to 2 pumps. Blowhole will save a little cash and I was planning on drilling the 55 gallon Im using for a sump and the 90 gallon display tank upstairs (currently in use - I know I've got brass balls).

I've seen some reviews of the blowhole saying it's a great pump - some of the early prototypes having a problem with heat though. That is apparently corrected with the final release model.

The Waveline is a really nice pressure rated pump, but more than I wanted to spend honestly - to bad the 5000 model wasn't enough only max 10ft of head.

I'll probably go with the Blowhole. What would you do?
