So Ran a search and found that basically J's ETD do work esp on high Mile's s2000 and track/street race apps.

Here is the thing, would this cheaper version on ebay work just as well as the J's version? I mean, it seemed to me that its the same concept.
Ebay Link

J's ETD

Price difference $150
thoughts??

 

If it's a quality product, can't see why not.
No JDM bling factor.
