In the future it would be great if we could keep the negative comments to ourselves until we know for sure it is a pattern.
That's a lovely sentiment, but it makes no sense (if no one posts until there's a "pattern", how could a pattern develop?) and as demonstrated by the numerous posts in this thread, happy customers will come to the defense of a company they've had a good experience(s) with.
I bought my Aida II used and it did not come with a stylus guard. I wrote to ask if I could purchase one and they sent me one for free.
I had a cartridge retipped by them and it was also a positive experience.
