First off, I don't know jack about lighting, it's not my expertise, so bear with me.

The previous owner installed Depos with the thick ring Angel Eyes (the word Titanium comes to mind). They look nifty, but I'm wanting to go to a more subtle OEM-ish look. So what I had in mind was selling / trading the Depos with the angel eyes and a new DDM 6K HID kit, and going with ZKW's with a HID kit.

I suppose my question is, what should I approx. get for my current setup, and would a straight trade for ZKW's / HID's be fair? Thanks.

its going to be very hard trying to find someone to trade with. if you sell them and are looking to buy some zkws, check out bavoys.com.
you cant beat their quality service and products!

I'm just trying to get an idea of what used ZKW's are worth, and what my used setup is also worth. I looked through a few pages of the Lighting classifieds and found nothing. I don't want to rip myself off in a deal, or inadvertently rip someone else off. Basically what would make it a fair deal. ZKW's for my setup + Shipping, or + $50 on my end... I need a rough idea.

using BAVTOYS.com the set up you want ZKW oem AE's and HID kit would cost $732.99 http://www.bavtoys.com/zkw.php

I don't want AE's, I'm getting rid of them. I guess I'll just throw them up and see what happens.
