Been playing about 6 or so years now, I personally don't know much about Dean because I've never used them, I know the name and know a few people who have them and like them, but in all honesty, you're better off starting with a better/better known brand such as Fender, Gibson, Ibanez. I personally started on an Acoustic and the moved my way up to Electric once I started recording, and I felt it was much easier to play.
Also, a quick tip, if you're just learning an instrument, don't learn guitar, everyone plays guitar, and quite frankly, its just not unique. I personally wish guitar wasn't my first instrument, but that's just me.
