I have one of the bottom of the line Korean made Sigmas.
It is a DM-1B. A black guitar. I bought it for $75. I
needed a guitar I could travel with and not worry about
getting banged up. This guitar is built like a rock. I
have bumped it alot of times with no damage at all. I
have also realized that it is my favorite guitar to play.
I loaned it to a friend of mine who is a banjo player
so he could learn a couple of Tony Rice songs. He has
has it for two months and I truly miss the guitar. It
is an excellent guitar for the price. I have others that
I refuse to play that are more expensive that the Sigma.
Now I play my Martin while looking for another Sigma. Not
to say that the Sigma is better sounding than the Martin
but my Martin costs too much to drag with me.

just my two cents...

I would recommend this guitar to anyone. Even though mine
is Korean made, I would look for one made in Japan.
