Trust me on this. I've tried PIAA, Razo, Hiper, Eurolite, etc. They may look nice but if you think about it... how long will they last? I FINALLY switched to HID because I got a good deal on it and even if those phony bulbs may "look" HID, the output is no where near the real thing. Let's look at it this way: hyperwhites last about a year(give or take) and you may spend up to $75 on PIAAs. That's $375 for five years. I spent $395 on HID and should last me the life of my car... think about it.
HIDs: superior light output, nice color, bragging rights
P.S.- you said money wasn't an issue
