First, what would be a reasonable priced one for a beginner? Specifically if there is one or model/type that I can sit down to play. While I can stand and play guitar for hours, I'm too much clumsy dork to drum standing up.
Secondly, since I mostly play rock/metal/punk, is there something I should be aware of with that harder style of playing? I have went through the forum and read some of the discussion in which loudness was discussed and that isn't a issue for me?
Third, can I get a decent kit for around 500? Government refund says I should help the economy

Please feel free to ask me questions. I'll gladly answer them.
