Cheaper alternative elec. fuel pump?

I'm looking at these carter elec. pumps that freeflow 100 gph, internally regulated between 6-8 psi, I never heard anything bad about them & hear they are quiter then the holleys, I was going to get a mech. carter HV, but alittle nervous about the diaphram blowing out & pumping gas in the oil. Is anyone useing one of these?
