For me, no contest in the lower price bracket; another vote for the Ozark tenor, about £200 including a nice hard case, from Eagle Music in Huddersfield. Loud, sweet-toned and a really lovely neck to play. Solid cedar top, laminate back and sides, nicely bound and finished. I play it in CGDA, although it really belongs to my wife and she loves it dearly. Rude not to buy one at that price, really.
In the more expensive bracket there are lots of luthier built tenors to choose from, but I'd be tempted to look around for an old Gibson archtop tenor. Getting pricier these days, but still plenty around.
