Behringer BDI21. Wholehearted recommendation - don't listen to the Behringer detractors, who seem to me just like the Squier detractors were 10 years ago. (Yes, it's plastic, but tough and solid plastic nonetheless.) I've had mine over a year now, used in all kinds of live situations, never let me down, and sounds excellent, even running as a DI straight into the mixer and on out through FOH speakers and wedge monitors. If you didn't know, you'd never guess I wasn't running through a "proper" bass rig. One slight caveat - does use up 9V batteries at a fair rate, and makes a hideous noise if you forget to change one! Plug in a standard 9V supply, and stop worrying...
