I have a ACDC LED Pro. It's our favorite pin (over the WOZ, Tron Pro, Met Pro). We had the original ACDC Pro but like this one much better (although they are pretty much the same). The bell is really nice. We replaced several of the leds (which are mostly white) with color leds (reds, blues, greens). If you can get one of these for $4,700 that's a pretty good deal in my opinion.

I have the ACDC LED Pro. There is a difference, actually a pretty big one. On the prem/le (if I am not mistaken) the metal "holder" part is on the left side (to the bells left and out in the open). Much more noticeable and not really balanced in appearance. On the new led pro the metal part (holding the bell) is directly behind the bell, not nearly as noticeable. Only the top flat part, behind the top of the bell, is really visible, to the player (a little bit of the sides but not much) . I read where Steve R. designed it just for this model. It looks good, it really does.

I just checked the manual that came with it (30 pages) and nothing is mentioned about the bell number. If you will call Stern I am sure they will give you a number (if there is one). A few months ago I needed a number for a Met part and I was given the number over the phone plus the best place to buy the part. The last I heard (a month or so ago) they were not selling the part.
