I am also a strong believer in the "you get what you paid for" saying but at Renntech "you get bent over for what you pay for".
I too was in the same boat when I was looking for perf. upgrades. Only reason I went with SI instead of Renntech is that SI was local to me so if something got screwed up I can easily go to their shop as opposed to getting stuff resolved over the phone.
Like Steve said it was pretty much just SI, Evosport, and Renntech at the time that had an ecu+pulley package.
Now there's plenty of choices and cheaper choices at that and more importantly a lot more people now have had first hand experience with them so peeps can now factor that when making a decision as opposed to the manufacturer just posting claims with no dyno or other proof.
