I'd get an amplifier. The second you want a speaker the cheap solution is not as cheap. VOX VT20x: sucks for metal, but most other things are passable. Easy to use, has a MID knob, headphones out, auxillary in to play along with something and gives you enough controls on the amplifier that you don't need the phone or computer application to get a lot of mileage. $180US new at most stores. It's so good it will stick around as a practice amplifier when you get something else. I'd also suggest the THR10, but it's $300US new.
