Bamboos are awesome looking, but I haven't even seen them for under 5k. Apparently a little too awesome. I got my calico pastel for 250 at a local repticon, but I haven't seen them under 300 otherwise. You can definitely find some good deals, either at shows or at the right site, but it can take a little patience.
I like the calico gene alot, those calico spiders are awesome looking. That's definitely a possibility as well
