Check out this site - http://autolamps-online.com . They sell a real HID conversion kit for most cars - ballasts and all. Pricey at between $400 and $700, but it's the real thing. Couple one of these kits with those plastic-shell conversion light kits (these claim to be safe for plastic lenses) and you'd have a lightweight intense light for under a grand. They also do an interesting trick - H4 single-bulb replacements that actually vary the placement of the filament to achieve high and low beams from a single light source.
