I have had a few different brands and the Meziere pump I have has been in service for over 4 years and flows like a belt driven pump. The finish and quality is obvious when you have one in your hand. They come apart rather easily for any servicing you might need without any trade tools.
Which ever one you choose i would go with a high flow piece. IMO
Alot of guys jump over that fact. The high flow pump will back up pressure in the block and heads behind your restrictor and raise the boiling point further to eliminate hot spots in the head.
