I got mine from
iPod Car Kit Direct
They were OK with delivery. Dension changed the model just when I ordered my kit. The Brodit mounting plate, that I ordered at the same time, came next day. However, I had to wait a month for the Dension stuff. But, ipodcarkitdirect kept me informed and delivered the kit as soon as it was available, so that wasn't bad.
As I've said before, avoid their recommended installer like the plague!
