For what it's worth, I bought a Martin DX1 for my son the Xmas before last. A good guitar, superior sounding to other DX1's I tried.
The only thing that bugged me about it was the quality of the machine heads. I eventually got it together to send away to Stew-Mac
for Grovers - and I have to say that there is a marked improvement in the guitar since I put them on a few days ago. So, Martin DX1 + High-end machine heads = a guitar possibly worth considering.
