That bad huh?I think it was this one from Smart Madness for $499: http://smartmadness.com/shop/index.php?route=product/product&product_id=360 There was apparently another aftermarket manufacturer that had a cheaper model but it did not get as good reviews and did not have the "speed boost" box.
Install was about half an hour. Just a couple of screws to get the steering wheel cover off, a couple plastic bolts holding the gas pedal down, and drilling a hole in the dash for the LED. That was the scariest part since he wanted me to do the drilling. I hate drilling into other people's cars but fortunately I did not leave a long scratch mark all the way down his dash. There was a 50/50 chance of that, knowing my track record. You should see me with a Dremel anywhere near a motorcycle frame, it is carnage.
$500 isn't bad for a kit made specifically for it; and it sounds very complete.
