Questions about "cans" in my area(KY).

[bsmith_shoot]

Im not new to NFA weapons, but completely new to suppressors. I live in the eastern part of KY, about an hour from Lexington. My first question is, where is a good dealer for "cans" thats close by? Im thinking an AAC can, a Surefire, or a KAC maybe. How much does the price in my area compare to the listed prices on their web sites?
Im not even sure of the model of suppressor I want. Its going on a 11.5 SBR, with a troy TRX 11" rail. I want as short as possible, and as quiet as possible, and still fit inside the rail. Any help or suggestions would be appreciated.
Thanks,
Brandon

Another question I have is, would a screw-on, or permanently attached suppressor be a good ideal? If so, what would my over-all length of barrel be?
Thanks,

You might try Rex Tyson in Nicholasville or Lincoln Arms in Bardstown. From what I've seen prices are close or slightly less than MSRP.
