It seems with acoustic guitars that you really do get what you pay for, more so than electrics. I have a Sigma acoustic (basically a licensed copy of a OO-style Martin) that cost around $180 new, which I never play because the action is terrible and no amount of fiddling with the saddle will fix it. And the main reason I haven’t replaced it yet is because I’ve yet to find another acoustic I like with a price under $3,000.
For the record, that figure is about twice what I paid for my PRS.
On lower end accoustics I’ve come to love the tone from a cedar-top more than a spruce top.
