I hope this trend of crappy HID's eventually just ends, lighting is a top safety concern and as such, you should pay the price that keeps you safe. TheRetrofitSource sells a $150 kit that replaces the H11 halogens in your stock headlights, as far as I have seen the Morimoto ballasts and bulbs are orders of magnitude more reliable than DDM or your typical eBay kit.

The proper, and slightly harder way to do it though is to replace the entire projector, which I'll be doing at some point:

It's $300, but you get the bulbs, new projectors properly matched to the bulbs, and brackets to adapt the new projector on. Dunston is one of the few guys to have gone this route but he's very satisfied with it and his lighting performance gained is definitely worth more than $300. This is doing it the right way, where the new projector throws the higher HID output onto a wider section of road and with a sharper cutoff to avoid blinding your fellow drivers.
