Just another possible is the Dbilas intake, tiz a quiet one though...so depends what you fancy.
I only mention because for some reason it seems to be the unloved intake on here and seems to often come up under £200 in the For Sale section.
That was my reason for going for it, good gains, quiet in use, cheap enough and the price didn't start with a 3.
It's def not eye candy like the Twintake is though. Depends on what you fancy.
