If the OP is absolutely set on having a real Moog...the Minitaur seems to be the Best Booming Bass Bang for the Buck right now. (say that five time fast lol)
However, given the type of sound you say you are after, I would encourage you to also look at the Studio Electronics SE-1 or SE-1X. You could pick one up used in the same ballpark as a new Minitaur.
I was looking at the Voyager, LP, Minitaur models but picked up an SE-1X for my bass duties and couldn't be happier (I seem to have become quite the SE advocate on this board recently

)
It has a couple of things I like about it that are missing from the Minitaur: primarily...the 3rd Oscillator. A majority of the bass sounds I program utilize this third OSC (to get that octave sound)...so I don't know if I would want to go back to a 2 OSC for bass. So for me that means Minimoog or Voyager (read: $$$)
On the SE you also get a Triangle waveshape for all three oscillators. Combine-able waveforms. 4 Envelopes. Pulse width available on all three oscs. 3 LFOs. 12db and 24db filters. Noise. An extensive modulation matrix.
...oh and no limitation to the pitch range of the oscillators.
What you don't get is USB / USB Midi, CV, that cool oscillator start sync thingy, or regular active updates / features from Moog.
( I may be missing some things...others can add... )
Also there is a common complaint the envelopes on the SE are not fast enough. I don't find this to be a limitation per se, but it is something to note.
For that funky, resonant, Zapp and Roger type bass sound (I call it Skate Rink Bass lol), the SE-1(x) will do it no problem. I think it's overall tone can come off as a bit more aggressive / dirty than the Voyager, but that can help cut through a mix.
Here is an example of the SE-1X with a resonant Moogy-type bass sound in action. This is a rough noodle / mix and the synth is being played in real time so the timing is off in a few places but you get the idea.
Zero processing done on the SE-1X this is raw into the Daw.
Best of luck whatever you decide.
