I just got the k840 and it was refurbed by M&R though Beacon Funding ( I think it was a repo ) then bought the omni bagger brand new and we so far have pushed just over 80k shirts through it and it is running like a champ. I would see if Beacon has another one since I remember seeing two at the time then buy the omni new. that was recommended to me since the bagger you can damage more easily!
pm directly if you have specific questions.
