what kind of guitar should i buy?

It all depends on your music preference. If you want to play jazz, rock and heavier music than you are going to want an electric guitar. If you want to play country and softer music you'll want an acoustic. If you want to play songs and sing I would get the acoustic, and if you want to have sessions where you rock out and really jam then get an electric. Now don't get me wrong, you can play any kind of music on an electric or an acoustic, I'm just trying to keep it simple here. An electric is a little tough on the fingers at first, but in a week or 2 you should get used to it. I know the epiphone electric guitar starter pack is excellent, it comes with an amp, a really nice guitar for the price, strap, picks, tuner, everything you need.

Most definatly a acoustic guitar. Starting on electric will rip your fingers to shreds. Get your self a nice electro acoustic, then you can use it in live situations as well.
