Are Speedmaster elec fuel pumps any good ??

70 Dart stock tank, adjustable module for ohms output, after market 3/8 fuel pick up/stainless braided line to carb, 750 double pumper, pressure regulator, incidentally I have read that Holley’s
Like 5-7 lbs of pressure, does that sound right. I am looking at a Speedmaster @140 gph. I was hoping that some one here had/is using
One and what the outcome is?? This one is $60 and that makes me suspicious. I know I get what I pay for. An equivalent Holley is $140, am I being too cheap??
