I've been doing the vintage thing for a while now (3-5 years) and haven't really found a reliable source at prices I want. Honestly if I end up with something that's a repro or a figure without, I usually end up looking for a beat up figure that comes with the weapon I'm after. Prices are usually the same as getting the weapon anyway and weapon lots on ebay often go nutty. Earthtoymall if it's still around is another resource, as is Cloudcitycollectibles in addition to Brian's toys.
