Oilpump 6.1, any better than stock?

up again. The pump of my old engine is destroyed. The pump from my sec engine has minor marks inside of the housing below the Rotors from a metal particle which got sucked into the pumb. I don't think it will cut oil pressure but since i replace everything i will replace the pump as well.

OEM pumps are very expensive here in Germany ( 450 EUR / 500 USD )

What about those Melling pumps? Are they worth it? Summit sells them for 130 USD for OEM Standard and 150 USD for HP/HV. For that Money i would import one.
