After I get my report card money, I'm either going to try and purchase a D. binata (multifida "extrema") or D. scorpioides. I really like the "Spiderweb of Doom" look of the binata version, but I hear that scorpioides are easy to grow and propegate, and have faster-moving tentacles.
If you have grown them, which would you recommend? Also, I'm having a bit of trouble locating online retailers that sell these plants. The shipping costs from California Carnivores is killing me, and I haven't been able to find them anywhere else.
