I would love to try one of those ^^^^^
Anyway, I have tried a lot of different things, and still go the modular approach, even when using modelers. The thing that has worked the best for me is the Source Audio Bass Distortion Pro and Source Audio Bass Envelope Filter Pro combo. I recently added a Line6 M5 for modulation.
Just this week, I received my Zoom MS-60B, and it does a really good job, though admittedly, I am still using the filter/fuzz/modulation/compressor modular approach with that, and it seems to be doing what I need. I will know more after this weekend when I will test it out with the band. The synths in this thing seem to track fairly well, and have plenty of options to play with, though, they just aren't doing what I need for my band. I particularly like the StdSyn and Z-Syn. If I were start anywhere this would be the pedal I would buy or recommend to start with since there is a lot of bang for the buck.
