Seems people here are a little upset that he gets the Craigslist deals, fixes them up and sells them.
Isn't that what a business is all about? Nobody here has said a bad thing about the quality of his machines, or his support after the sale.. so it sounds to me like if you want to buy a ready to play machine, he's a good choice.
If you want a deal you can fix up and shop yourself, beat him to them.
Seems pretty simple to me.
