Is there a reputable place to buy ready to use vintage hand planes? I am new not only to hand planes but woodworking in general so I don't trust myself to know what to look for or how to refurbish one yet. Currently I only have a Kobalt number 5 bench plane and block plane but am looking into buying a large jointing plane like a Stanley number 7 to flatten some slabs and the workbench top I am about to build.
Also what should I expect to spend for an old Stanley and ready to use condition? I'm not looking for any sort of collectors item or beauty queen just a ready-to-use Workhorse.
