Looked at a kit recently with the same business going on internally.
I've seen other drums internally similar but sound the way they should (i.e. not warped). If this is all that's going on & you're going to play it and keep it, and especially since you've been wanting one exactly like it, I think in the $900 would be fine (but bargain intelligently as far down as you can). But all I've seen is the inside of the BD. It is a Downbeat after all.
What color is the sparkle?
