Hello, Sardo. First, welcome to the Forums. We're just as glad to have you as you are to be here. If you've just joined the NAFC as well, welcome to the Club, too. Enjoy.
I don't know where you live, but I've seen the unleaded weights at the BassPro in Gurnee IL at the Gurnee Mills Mall. They have the leadless jig heads there, too, if memory serves. If all else fails, you can always order them by snail mail from BassPro. It takes longer to possess them, but you will have them in your arsenal eventually.
A second recommendation I'd give you is to fish without weight whenever possible. It's a more natural presentation, and I believe more fish are caught when my offerings are weightless.
Again, welcome to the Boards and the Club, Sardo. Tight lines and slimy nets to you!
If I'm not fishing, I'm thinking about it. Keep the line fresh, the hooks sharp, and have fun fishing. God bless you. -Sonny, Life Member since 2002
