If your considering a Greddy type s, then check out the NGR Type S. Currently they sell them on ebay (they're building a site), but they aren't "Ebay junk." They are made from a Greddy type s, but with better internals. If you want to hear them go to youtube.
By the way...try a search next time. I think this is the third bov thread in like a week
I haven't bought one personally, but from what I've seen of the one's friends have used, the NGR Type S absolutely does not have better internals. It's true that the internals are basically the only difference, but that's the problem. The diaphragm of the NGR has been known to fail very easily.
. Thats the first complaint I've heard.1g BOV, this little oem part is has proven itself to be an awesome blow that is designed to recirculate.
If you are planning to run more then 17 psi, then this isnt the BOV for you unless you modify it(You can search the forums for that) or purchase a modified version.
I am currently running the HKS SSQV. Its pretty damn loud even recirculated.

Just stick with the 1g BOV. Although if you're shooting for mad power then go with Tial Q BOV.
