External vs Internal Sump Pump

[Digger]

After my disaster trying to drill my sump tank, I'm having to change from an external to an internal sump pump.

Here is what I was going with...

PanWorld 100PXX

Here is what I'm thinking about going with...

Eheim 1262

Aside from the obvious difference, would they be comparable? Does anyone have a better suggestion?
My main concerns are heat generation and reliability.

The panworld one has a bit more gph to it, that might make a difference depending on what you are using the pump for as far as tank size and overflow capability.

I have 2 mag drives running internally and have had no heat issues yet. I also have a rio HF running on my 125g and have no heat issues with that either.

Thanks Carey!

I'm using a 55g as the sump for my 125g DT. My overflow should handle about 800gph. I was thinking of going with two smaller Eheims and setup two returns instead of the one. A little bit of redundancy and I can match the overflow capability. What do you think?
