i think most are new fairings ($500ish for a set, wouldnt call them cheap exactly) a guy in my riding group has a set of red ones on hits zx10r and while i didnt get to take them on and off to see what the inside is like, on the outward appearance they seemed just as nice as stock.
alot of them are wraps too, theres several shops here that do full custom sticker jobs.... a few are paint, but this is probably the minority, paint is such a pain in the ass.... wrap is easy to go back to stock, and fairings you can put the stock back on and sell the custom ones separately.
