Kawa Bonsai's winter show is in a couple of weeks in Flagler County. They have some great headliners this year - William Valvanis, Ted Matson, etc.
There will be multiple vendors there with tons of stuff for sale. 15 bucks gets you in the door; for that you get to see the (always nice) exhibit, several demonstrations and the vendors' area - real pre-bonsai, 'finished' trees, pots, tools, raffles, etc. I highly recommend checking it out. I can't make it this year as I'll be digging cypress at Adam's Ranch (don't tell Ed).

Also, about 2 hours South of you is Jason Schley's nursery. After a few visits there, you'd probably never look around Home Depot for bonsai material again.
