karl,
look at some oen who is doing well at what ever distance you are looking to race at. Get their number have some rum and ring them up. Make a little list of some questions you would like to ask. That way you get over the nerves of cold calling. If they sound like nice reliable people ask if you can have a look at their birds. Make a visit and don't be too pushy about buying but ask if they sell when and how much?
It may not be possible to get to someone in your local club area. They are trying to beat you so think outside the box.
I often drive an hour to see my buddies and some I have yet to meet, only ever spoken on the phone, Amtracked them to me, the birds etc.
