See, I don't even stock the BR-70 becaue to me there's not enough value in the purchase to warrant it over the BR-60. Here are the differences between the two: BR-70 has Brazilian rosewood laminate back and more abalone inlay, the BR-60 has "choice" rosewood laminate back and less inlay. Now, I have played instruments in my life where there was no doubt the Brazilian rosewood was THE DEAL on the thing; it really had a voice. But I can't swear I get that kind of reaction here because it's not a solid back. Sure, a solid back of Brazilian rosewood would be a huge difference of a laminate back of "choice" rosewood. But if the added inlay and the idea of having some Brazilian rosewood floats your boat, go for it! There's no bad purchase if you're happy w/the guitar.
For me, the BR-60, and it's 000 sibling the BR-63, is the top of the line model I stock in my store. $400 w/a case. Not too many first time guitar purchasers are going to plop down more than $400 for a guitar. But I've certainly played higher end Blueridge models.
