inline pro would be my first choice and rev hard would be my second. both are pretty cheap and very good quality. SFP is a great manifold but a bit more money and honestly I have never bought anything from them before so I can't tell you what customer service is like (I have heard they have very good customer service). I have bought from inline pro and had a few friends buy from rev hard. very good stuff and like I said the price is right


PS- I do know SFP has a 10 second civic with AC and PS though so I would say their stuff is pretty damn good too
