I think you may be mistaken about this K C M.
It is not at all uncommon for people to sign up on eBay to buy just one select item that they are in dire need of. What you are suspecting is called
shill bidding
I am an ebay junky and have been a registered user since it's inception. I am part of an (unofficial) eBay support group the investigates and assists other members with fraud issues. You can find me in the community forums as well.

Shill bidding is usually obvious if you look at trends of the sellers past sales. I looked him over and while I did find one user that did bid on two items from this seller, I could not find any evidence of shill bidding. I have exposed many shill bidders/fraudulant sellers and this guys patterns do not seem to indicate that is the case.
The bids on this item are typical of nibblers (bidders that keep upping their bid in small increments so as to achieve top bidder status instead of entering the maximum they are wanting to pay and walking away)
On the contrary, the seller appears to be very honest. He leaves feedback first and has given more than he has received and the comments on his profile are stellar. I would not be afraid to purchase an item from this person.
