Getting back to the OP's original question.

I bought the Mercier Kilo OS from BD and a set of S3X IGH wheels from their associated company Bike Island. Both items arrived promptly and with no damage other than some minor scrapes in the black spoke finish on the wheelset. Both the items I bought were made in Taiwan rather than in China per the markings on the shipping boxes.

The front wheel on the Bike Island wheelset was slightly misdished. All four of the wheels received needed minor trueing. Overall the bike assembly was good though there are few things to mess up on a FG bike.

I bought the Kilo OS from BD because I liked the dual top tube frame styling and I could not find anything similar anywhere else. Some of the offerings from BD such as the Mercier Kilo OS and Mercier Kilo WT 5 Speed are not available configurations from other sources other than as custom builds at much higher prices.

BTW I am a supporter of buying from a good LBS if possible and have bought 3 new LBS bikes in the last two years.
