Looking to get a Quick Fuel 30-175

I'm looking to get this pump/regulator setup.http://www.summitracing.com/parts/qft-30-175/reviews/
My only concern is, I cruise my car. I've read that some electrics dont like to constantly run. The price is pretty good on this unit, and I like having the regulator right there and not having to mount it elsewhere. I've also looked at the Holley 125.
Holley 12-125, Holley HP 125 / HP 150 Electric Fuel Pumps | Holley

Not sure what to do... Any insight would be appreciated.
