I got mine second hand (insolvency auction) for $900 for a machine that would have cost $6,000 when it was new a couple of years ago, and later I spent $400 on a grinder that goes for $1200 new. Both in good working order, apart from having to replace the hopper on the grinder ($70 for a piece of plastic was annoying).

Totally worth it though. The grinder (and coffee beans - buy them no later than a week after roast) are the most important part really.
