I think that I can safely say that I've messed with all of the bigger name stuff, except the new AE RC8. Of all that I've seen, messed with and converted, the X-Ray seems to be the best available right now. In terms of fit and finish, the XT8 kit is second to none. If I do another conversion for myself, it will be an XT8.

Even if you don't think that the XT8 is the best going, you would be hard pressed to make the argument that going with the XT8 would be a bad choice.
