Billy,
Those of us who like Carpenter Gammas or Bluefish have had to develop a Zen like attitude to picking up lures.
For whatever reason, these lures are highly prized and the only advice I can offer is that you have to have patience.
They do become available, and sometimes quite easily, but their distribution is fairly tightly controlled and your approach has to be more strategic than trying to pick up something that's readily available. They tend to release one style, size or type at a time in whatever color combinations is currently in the catalogue.
Carpenter Lures Australia, Saltywater Tackle and Ocean Active are all great sources of the latest release. I've also found Fishhead in Brisbane and some of the Japanese stores like Plat and Pro Shop Mogi a source of lures. Don't try and play the ends off against the middle though, develop a rapport with a supplier and you'll be amazed.
My advice is to not get involved in the secondary market which can get silly, even for relatively ordinary lures. Gammas and Blue Fish are great lures in the right circumstances and with the right approach and a little patience you can build a decent selection without breaking the bank.
Just my thoughts.
