I bought the Eastern Music "Power neck champagne gold color tenor saxophone SBA style neck with warm sound" with the 28.2 mm tenon to go with my Conn 10M. I'm still putting it through its paces now (with a variety of mouthpieces), but my first impression is quite positive. It fits perfectly and sounds great. Intonation is fine. While I'm still trying to wrap my head around the sound of this neck, so far it is comparable to the stock neck. For $79 US, highly recommended.
