I use the ART dual channel mic pre; it's not too bad. You need to experiment a bit with the input VS output dials; you can easily get too much punch and distort a vocal; on the other hand, you can get it right to the right point on your dials/meters and get some great stuff.
If you're real rich, try to audition the MartinSound Mic preamp. It is supposed to be VERY GOOD. But, it runs more than 1k.
Keep twiddling the dials,
