OK all of you skimmer experts, I need some input.

I have been researching skimmers on the net and have narrowed it down to a few possibilies in my price range, here they are:
1. AE Tech super reef devil, rated up to 180 gallons, $200.00
2.Aqua Medic Turbo Floater 1000 with needle wheel pump, rated up to 250 gallons, $185.00
3. Tunze 0220.3, rated up to 400 gallons, $236.00
4.Pacific coast imports, PS-400P with needle wheel pump, rated up to 400 gallons, $190.00

For those of you that are familiar with these skimmers, any advice would be greatly appriciated.
