i like to build good value. not cheap, like used stuff, just not expensive.
this is why i always use sun m13ii rims and sapim db spokes. you can probably get a 28mm tire on there, but i only run 23mm paselas.
my last set of rims came from niagara cycle at under $33 each shipped. danscomp provides the spokes and nipples.
i'm getting a lot better at building wheels, but it still takes me a weekend to do it. i just use an upside down bike frame as the stand. works great.
