Yo Skipping Hopper de Be-Bop:
There are great deals on mics currently. Best to try and hear one or rent one to see how it jells with your equipment.
I, too, have an ART dual pre-amplifier; however, if you've got the bucks, the Martinsound Mic-Max has very good reviews and is a top-end product; it currently goes for 1400.00 dollars, give or take a few.

Keep hippin' and hoppin'
