Sax is hard, ive been trying to learn it for afew years now, although obviously not alot of time spent (due to guitar/bass) but I eventually want it to be my main instrument. Its just the best. Altho I will miss some of the speedy shred stuff you can do on guitar, which is gonna be SUPER hard to do that fast on sax, I think it'll replace all my complaints about guitar as an instrument.
As far as the sax itself, looks nice and shiny but its hard to say how it compares as a player.. One thing I found out unfortunately is that Sax isnt like guitars; you cant just buy a cheap $100 sax and get it to play decent enough like cheap guitars can.. Although maybe that one is fine, obviously cant tell until you try multiple sax's. I will say my $200 Vito Alto (which is made in the Yamaha factory apparently) is very hard to blow thru, compared to the Selmers and other horns I tried at the store recently.
Sax is a very expensive instrument to pick up, if you want a super easy-blowing strong tone sound =[ Im about to drop $2000 on one soon, and its not even a pro model lol
My advice as far as learning to play; Get a teacher.. You can blow into it and it will make notes, but getting the proper embrochure and exact way to use your breathe (almost like singers need training) is the key, and that is where I fail right now since I havent taken lessons yet.. I can play every note up and down the sax, but without that proper training I dont think I can go much further than this.. Teacher is quite important for improving fast on Sax, esp if you already know enough theory because the hard part of the Sax is actually playing it, unlike guitar where the hard part is the theory/knowing every chord position.
