I switched from Alpine to LUX. Had some iffy customer service from Alpine as well.
Also, even if it's isolated, I'm not taking a chance on yellowing. And at night the HID kits = a blob of light. Sure, they are bright, but I got complaints from guards at the military bases I drove into to turn my headlights off, when only the angel eyes were on. Can't be bothered to turn DRL's off every time I come into the gate.
LUX was the best for me. Bright enough, but not so bright that it turns into a blob of light when the headlights are on too, and very easy to install (no wires coming out of the headlight housings).
