Good luck. Obviously, I can't spoeak to the merits of this particular instrument, but the model is a good one. Of course, the 000-28 (EC or not) is also a good model, individual variability notwithstanding. For myself, I find that the bass response on the M series instruments is more satisfying than on the 000 models, but it's really a matter of personal preference. I wouldn't be too worried about water stains from an overfilled Dampit (pretty common, and not too serious, as long as it wasn't such an egregious situation that it caused structural damage), and the "shaved bridge" may just mean that they lowered the saddle as a concession to a previous owner's tender fingertips (again, pretty common, and easily rectified if that's the only issue). But going wiht your gut is the right thing to do. For myself, I would be very hesitant to buy any quality instrument -- particularly a 20-year old instrument -- without having first cradled it in my arms. Happy hunting, and don't rush it -- with patience, you'll find the one you want.
