I am always suspicious of bidders that have a high percentage of bidding with one vendor:
geekified (winner): hasn't bought anything on ebay since 2003
d***r: 50% of 8 purchases total
e***m: 7% of 75 (looks ligit)
T***T: 0% looks ligit
h***a: 100% of 102 purchases
y***o: 100% of 40 purchases
t***m: 33% of 474

bidders must beware of sellers bidding there own goods up. They can always offer you a second chance offer... so they are able to get as high a price as you bid.
