All in--I paid about $650. I got upgrades for all LED on the brake/tail/turns. I paid extra to get an H4 Hella 80w/80w headlight, and I purchased a new red tail assembly and license holder. Also, I paid for a brand new upgraded stator from Ricky Stator (dual output 100w/100w). The system works fantastic. The headlight remains on AC and is fed by one of the stator outputs. The brake/tail/turns/horn all feed DC off a battery that is regulated and fed by the other stator output. Simply awesome.
Oh, and I got a second mirror, as it only came equipped with one from the PO.
