What internal pump to use otehr than a good ole MagDrive 3, 5 and 7??

[Mr James]

I have always used them, but since there is a whole new market out there, what internal pumps compare to the mag drives?? I am in the market to buy some misc pumps, but not too sure what to get. To be used for misc water movement, like moving water from one tank to another or a temporary return or drain for water changes, ya know!?!
