I've got a 00-18, got it because it was beat up and cheap in the 70's. It's only got a decal on it, no inlay, except maybe a bit around the sound hole. There was a female country singer had a line about her 0018 Martin a couple years back. Otherwise they live lives of quiet obscurity. I've never felt the need for another guitar. Maybe that's because I'm beat up and cheap in the Double 00's.
