I think most of the cartridge owners are not an experts (including myself) and few of them ever seen a stylus or cantilevers under a microscope. It's very difficult to judge about retipping service, once a cartridge is back to life people are happy and will leave a positive feedback, because the job is done and the price is low. The ebay feedback is really nothing in this situation, it's important who left the feedback, for which cartridge, how knowledgeable it a person who left a feedback.
And the most important question is why do you want to retip a cartridge if you can buy another fully original cartridge which can be much better than your previous cartridge or/and very close in pirce to the cost of retipping service alone.
