Evan, I've owned a Shinon Red Boron since new. My first one was replaced under warranty when the cantilever collapsed after about six months. The second one has lasted all these years. It has not been in continuous use so it is impossible to estimate the hours but it still sounds great with no indication of high frequency distortion from wear, even to much younger ears than my own.
Through these years of ownership and enjoyment, I've described the Shinon as a bargain Koetsu. It has a similar warm, organic sound while still offering very good detail, soundstaging, and extension. Bass information is limited mainly by source material. I had not priced the Soundsmith rebuild but already decided I should send it to them soon for a check out. Seeing the price you quote (new tip and cantilever?) this will be a no brainer! I can't imagine another cartridge anywhere near this performance for this amount of money
