I've got those mirrors too, they're not bad actually but I must admit that the OE ones are cooler looking... Not easy / cheap to get hold of the originals it seems as I've been looking for a yellow pair for over a year. Good luck dude!
I cant justify that sort of money for a second hand unit. I wouldn't mind a swap though. The retail price of these DP mirrors is also ridiculous but don't mind losing out there.
