almost any shop can get fixed/ss stuff, but most wont stock it, but if you know what size you need (and if you dont just get sized) they can order stuff, most shops get supplied by qbp, and they have almost everything under the sun, if your doing a custom build from a shop (ie not getting a frame online) i think pake would be one of you cheeper options, and i believe most shops can get those frames, i know the bike shops at REI can get em, and those are all over cali

disclamer: i work at an rei, thats why i know what they can get, not trying to go onto forums and push rei or anything, just what i know (besides i get payed hourly, how the company does doesn't effect me)
