Thats a pretty good price for that bike. But, you should forget about the wheel trade. You are going to pay way more for custom wheels than what you'll get back in the trade. Ask them to adjust the wheels that are stock on the bike. That should be free if you buy the bike. If tensioned properly by hand, they will last years without needing adjustments and will be basically as good as handbuilts. Good spoke tension makes great wheels....the components are secondary. Ride the stock wheels 'til they die...then go for custom handbuilts.
