nt1200,
In my opinion its better to spend an okay amount of money on a "quality and proven" product as it turns out more reliable and cheaper in the long run.BUT ofcourse if you can find something cheaper and proven to work for your application thats good too.
I'm planning on using a Nismo electric fuel pump when i put the vehicle on road.They are being sold on ebay for au$183.75 plus au$33.85 shipping to oz by Bprojects Brand new.

Features.
This pump is an excellent pump of the longtime seller in Japan.
It is very liked by a Japanese and widely copes until at circuit-driving and street-driving.
Please install a fuel sub tank if for competition purposes.
And add this pump. the dual pump system is high-performance.
