I have a 4000, 6600 and 11,000 plus I have a gem. Love them all. Look on ebay. I found my 11,000 on there for $3000.00 and it had been gently used. Got it 2 years ago and love it. Use my 6600 daily and also is a great machine. Also if you check on ebay a lot of times they have new machines at a very reasonable price.
