i don't know if you'd be interested or not; but you may want to check out the Rick Turner Renaissance RS6 w/ his new "the deuce" humbucker option. I just ordered one, and am looking forward to getting it in soon. I'm bet you could order a lefty from him...Here's a thread where Rick talks a bit about "the deuce".

These are close to your price range (may be cheaper than a T5 with K4) and have a great reputation for awesome acoustic sounds.
