the 711w is not an entry level machine, you do have to make mistakes with it to learn how to get it right!
I would definitely buy new with great training and installation from The magic touch instead of buying for 2/3 price second hand and no support.

You also need a very good press, TMT won't even sell you the box's of media if you have not got a good press and rightly so as you would only be frustrated with poor results.
