That's what it costs to upgrade to real Xenons (HID's). This is because of the need for the extra power supplies. HID's cannot be retrofitted to high beams because the size of the bulb positions it in the headlamp in such a way that the lens will no longer function effectively. However, JC Whitney also sells an aftermarket setup (also $1000) which can be mounted externally. If you're just looking for "blue bulbs" (aka "Rice Racers") just check your owners manual, I think they're 9005 + 9006 (high/low).
PS "blue" bulbs, as well as potentially being illegal in most states (depending on how blue they are) also actually degrade the performance of your lights by blocking the yellow spectrum. If you're looking for a different "look" try the yellow-tinted bulbs which actually remove the blue spectrum and provide a higher definition, thus improving night performance (they are also known as "all weather" bulbs). BTW "Rice Racers" actually look yellow when you see them unlit, "all weather" actually look slight blue when unlit.
