First off, I suggest not using a laptop. They're just not robust enough for a shop environment. Second, the computer requirements for your PRS are really quite modest. Go on eBay and find a computer recycler who will configure a refurbished machine to your liking for about $150 delivered to your home. I got one that was the size of a dictionary that works perfectly for my PRS Alpha.
