Hey, Drew, as a present recently I received a cheapo keyboard.
Go get one!
The idea was that if I kept my interest in it, boy-o will buy me a REAL GROWN UP keyboard. Woot!
I love it. My musical background is "play for fun" and like you, just a bit of guitar and such.
It's fun, and there if you go with a cheap keyboard and love it like me, you can always upgrade to a piano or start falling in love with the keyboard as I have...and want a big 'un.
