I'm using a BBE Bmax (the cheaper solid state one) that I actually like more than the sansamp bass driver DI pedal. Having parametric mids from 250hz to 1K is really nice (and the sonic max is true bypass so you don't have to use it). There are some that actually like the behringer clone, but I have never used it. I have also used (although very little) the Tech 21 RBI and that was also really nice.
If you can spring for one, even if it's a pedal snag a compressor if you can. I think hardware does a better job than software in the case of bass (just personal preference).
Of course this is just what I like though. I do not care for going direct through the sound card and using plugins to shape the sound, I know many do but I have never liked the way that has come out sounding (even using IK's ampeg amp sim).
EDIT: I have a Fender American standard Jazz bass.
