Looks good. The black and blue colors are nice with the silver engine. The bike looks like a hearty old steel frame, am I right? I usually don't like cantilever brakes, but they get the job done once you have them set up right. For spare parts, try www.niagaracycle.com . They sell replacement parts for retro bikes, good budget stuff, tons of tires too. You said this was a budget build, but looks like you did really good.
