Need a new amp, hopefully for around $200. I mainly play alternative rock and some punk. Any suggestions?

Take a look at the Vox VT 30 or a Roland Cube or something dont know if they will be better than the amp you have.

That's a no go, in my opinion.

Go with what rabguitarlegend said. Vox or Roland cube.
