the martin alto saxophone

Hi guy, I just bought a "The Martin" Alto sax for a little over $600. What do you think about this horn? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260632586042&ssPageName=STRK:MEWAX:IT

Hi guys, Saw this video when I was browsing and it was amazing. Does anyone know who this saxplayer is? What mouthpiece do you think he's using.. Enjoy...
