Paul;
If you're on the fence, then wait until you can attend the next UKLEM on February 3rd. I'm sure there will be at least one member there that will have a Flashback 3 controller. (There will probably be a couple Mamba Black users there too, along with a few Pangolin QM-2000 users.) You can ask the folks there how they like it, and you'll be able to see it in operation. Then you can decide for youself if it fits your needs and your budget.
