I love my Ruby - it's the best purchase I ever made. You definitely did not pay too much and got a great deal, especially considering it came with 105 and Look pedals. If you had bought it new, you would have paid almost double that

Specialized Ruby 2011 - $2700
Look Pedals - at least $120 (can be more depending on the type)
bike computer - at least $40 (can be more depending on function)
specialized water bottle cages - $40 each (carbon)

At the end of the day, you have a wonderful bike which in my opinion is priceless. Enjoy it!
