Boy I'd really stay away from the Fishman Matrix Infinity. Outside of being super expensive, they are really too heavy and bulky for ukulele. I've done a few of them but I won't install them any more. It's awkward adjusting the controls inside the sound hole and the tone control barely works. Between the the preamp, the battery and the volume, tone and bass control, that's a lot of stuff to crowd in a small sound box. There's hardly any room leftover for the notes to dance around in!
I currently am a big fan of the Mi-Si simple jack with either the the Fishman or Baggs element. Simple and effective.

E-lo, give Bob Gleason at Pegasus Guitar a call and he'll be glad to send one out to you. (http://www.pegasusguitars.com/) He's the only one I know of who sells the combo you mentioned with the ukulele sized Fishman pickup.
What is it you don't like about the Baggs?
BTW, the Mi-Si Trio consists on the preamp and endjack, all in one, and MiSi calls that assembly the "simple jack". I'm guessing that the "trio" part is the UST element which in the case of MiSi is a Baggs element that is already soldered to the preamp board. If you use the Fishman element you'll need to use a LOW wattage soldering iron to do the job.
