If you decide to get anything from
Brussel's Bonsai, I'd wait until they're having a sale, which happens pretty regularly throughout the year, especially around major holidays. They have lots of material that is fairly priced, but also some stuff that is ridiculously priced as well.
Glad to help! Crape Myrtles can make good bonsai material, especially the dwarf varieties if you have the patience to let them grow. Plus, they LOVE the Carolina heat. If you're looking to get one from a local nursery, be diligent in your search to pick a specimen that already has some natural movement to it. It'll save you lots of time later. For example, here's a dwarf variety that I bought a couple years ago with the intention of making it into a bonsai. However, it's been enjoying life as a potted patio tree instead, and stands just 14" tall above the soil. The trunk and branches already had all this great natural movement, and I've simply been selectively pruning it since then. It'll probably end up as a bonsai someday.
