I don't know how much of a hurry you're in to grab an acoustic- I know the Seagulls are consistently good, and I enjoy playing a friends Seagull 12-String.
I own a Yamaha CPX-15E, and previously owned a CPX-15SA. IMO, the E FAR surpasses the S in tone... must be something to do with the quilted mahogany body rather than white sycamore. Anyhow, the CPX-15E I own now is the best feeling and sounding acoustic I've ever played, and I've spent a lot of time in those 'acoustic rooms' in Guitar Center trying out the $$$ guitars. Warm, full but not too bright tone. Just nirvanic. Plays as easilly as an electric as well. I've found these on eBay every now and again for under $600, and actually bought the S on there for $500 in mint condition with case.
BTW- you can buy it new for $600 on an online site. The name of the site rhymes with 'sounds'. But has a couple z's in there. This is a crazy low price for this amazing instrument.
Just another opinion.
Oh yea- and I have a Takamine similar to the one you're looking at. I actually have the 12-string version. IMO, the tone is a bit brighter than you'd want in a 6-string, and lacks a little depth. Good for a 12 though. Then again, some people love that brighter sound. Ice cream, eh?
