I had a question for anyone who has taken apart the 8900 -- exactly how hard is it?? I used to have a 83-- and I became very good at taking it apart and putting everything back together. I often changed the housing. I would like to add the black bezel to my 8900, but it just looks like it's more difficult to handle, even after watching the video. So my question is, 8300 disassembly harder or easier than 8900?? Thanks!!
