Testing waters 'dual projector kit'

So a few people have asked me on the dual projector/bi xenon mod and now I was wondering on what to do about pricing.

So here's the thing, the kit would include two dual projectors for the hi/low beam and the brackets necessary.

Installation is simple, only difficult thing is opening up the headlight. Once you manage to open up its a 10 minute mod. End results is way better beam display

So here's the question, how much would you be willing to spend on something like this. Bare in mind, be reasonable.
