I, too, use the Peavey Escort, with a separate 4-channel powered mixer it copes with guitar, electric fiddle, mandolin, melodeons and two voice channels. Good value for money, robust construction and reasonable power make it adequate for most gigs IMHO. Plus it's easy to shift around and fits in the car boot (trunk). We use Peavey, Turner-Conrec and Shure mics, Shadow and Fishman DIs.

In my youth we got away with a couple of Vox AC30s and a 20w Linear Concord PA with Reslo ribbon mics. Perhaps audiences were quieter then!
