It is definitely worth buying a used machine. You typically gets lot more value for your $$$. The price also looks pretty good if you will get local support for the machine (classes, warranty work, etc.). I definitely think you should ask for classes to be thrown in with the machine for that price, if you get it.
You might be able to find this machine for less on Craigslist or eBay, but there is more risk associated with those purchases. Check "completed listings" to see what this machine has sold for on eBay (only the green prices indicate that the machine actually sold):

Edit: I ***love*** my Bernina 1260, but would not like to be sewing on any of the Bernette machines.
