Honestly, I REALLY don't think you should get one.
They are EXTREMELY complicated and if you have a busy schedule, they really are no fun at all.
The games are boring, the characters aren't really cute unless you take EXTREMELY good care of it, the Music City isn't fun unless you are constantly on the web and become really successful, the buttons response is slow; it's not a fun Tamagotchi.
It's too complicated to be a cute little egg-pet. At least, in my opinion anyway. The Music Star is the worst Tamagotchi that I have ever played with. (And I've played with all of the connections and some oldies)
