I have had my eye on that machine myself for a while now mate, but a few have complained about there service, and the use of RMA'd hardware ( what does RMA'd mean its in tip of tounge).
So I hear you have no end of techincal issues with a machine from them if its wrong, and no end of issues getting it sorted.
But I will watch and see if others aint had such as bad time as some people I have met online.
