HIDs… Who sells a good setup today?

With all the rage in LED bulbs, I am interested in a set of HIDs for the GTO. I have LEDs in there now and while they are decent, I can’t help but drive my wife’s Acadia with factory HIDs and like them more. I probably shouldn’t be worried too much about this since I don’t drive the car much at night but I would still like a good light set up. I have a spare set of headlamp bulb covers to modify for the bulb wiring and I don’t mind running a heavy duty wire and relay setup to the battery if it is needed. So, who is a good brand/vendor to buy from these days?
