You can do it, Willy!

I got
formulas/suns=dura ace lockring&soma Cog, and some other crap for less than 2 bills
bought RD's and a BB online-42.50
I had tires, tubes and pedals, headset (14 bucks)
plus bribing someone to help me take off/ put on things ( I had it powdercoated)

still less than 500 bucks, including the bike and powder (~250 between the 2.)
