For a SSB cb you can't beat the Uniden Grants. I would put those first and seconded by Philipine Cobra 148. No China shit... Now there may be some really great SSB cb's that go way back but I can't give specific models. The old Tram mobiles had some unreal audio.
Uniden PC 76 which is only AM as I know you know, are really good audio output machines but you want SSB radios. The Grants may not be huge power monsters or "the" loudest radios out there but when you look at the cost and reliability and modability they are tough to beat. I think properly tuned Grants and 148's are probably, pound for pound, some of the best radios out there. I am re-thinking my desire to get an export radio, although the SS 158 EDX really has me interested.
