Quoted from Kozzi:As such I'm looking into getting my first machine and have decided to get a new machine to avoid possible technical hangups.
I did the same thing last year for similar reasons. I chose a machine (Aerosmith pro) that didn't have any complicated mechanical devices and is really easy to maintain/clean as well as it being a fun game to play. I know this isn't answering your question but if you're not too tech/electrical savvy like me, this is might be something to keep in mind when buying your first machine as well. Definitely try before you buy as well.
The guys at AMD are awesome if you're using them. Good Luck
