It was nice to met you at the match northernbird. Any good comp that I've seen is going to be loud. Yes some are louder than others, but they are all loud. As far as I know there's just no getting around it, at least until suppressors are legal here in MN. That said, it's almost a necessary evil if you want to excel at 3-gun.
As mentioned above the Nordic Corvette comp is a good comp without breaking the bank as is the DPMS Miculek brake.
I've got a Benny Hill "Rolling Thunder" comp on my personal 3-gun rifle. The SJC is very popular with shooters as well.
Good place to look for a good deal on a used comp is the classifieds over on the Brian Enos Forum. 3-gunners are constant tinkerers and always looking for the latest gadget that might give them an edge over the competition. The last "best thing out there" gets sold over there on a pretty regular basis.

Careful.....they come with a side effect of itching and burning.
