$11,000 It depends which 830 you are talking about. If you mean the classic 830 record, I just checked on ebay and in the last 30 days(today is 9/10/12), they are averaging around $450 to $500 dollars. There were a few for less(295-400) and even one at $1000. It depends on what they came with, their condition and if they had a warranty. If you are talking about the newer 830 sewing and embroidery machines, 3 sold in the same 30 day period, 2 in the $8000 dollar range and one for $5,000.
830 of them.
