Your price will vary depending on the dealer that you choose. You are looking at around ~1450 for a standard kit, but that may go up slightly when the upgraded system is released in January. If you plan to tune it yourself, I'd pay a little more to get the support that comes along with going through a reputable dealer (ie, not ebay). That being said, check the EMIC list posted on the web:
Find someone near you, and be sure to ask them if they have been to the Gen 7 training class. That will go a long way to separate the wannabees from the serious tuners.
