Your email sounded like you were rather very busy
After speaking with Cary on the phone this week, I'm leaning towards a piston type pump as I probably will not run it 24/7, but put it on a timer for most of the time. One like this:

Then there is this pump, probably been posted here previously and might choose to run it 27/4 at 2.75 amps at 220 VAC. I've got a 220 line to use, but It might be convertible to 110.
