If you don't have $2k to put up as a deposit for a turbo kit, where would you get ~$5k for a completed kit? let alone the money to have it installed? (from the sound of it, you wouldn't be able to install one yourself anyway)
Think about the probe, it has been around for far longer than the Contour, giving probe owners far longer to develop a kit for it.
besides, why is a turbo kit so necessary? If you are in that big of a hurry, build your own. Otherwise, sit down and wait for Mr. Hightower or Mr. Haines.
