Got a 1968 Martin D-28, last of the Brazilian rosewood, before which I've had since about 1972, it sounds better every day. It paid off my mortgage, put my son through a special school, and is referred to as 'Grandad'. Love it. The price is forgotten as the quality is constantly appreciated.
Have a 1972 D-18 which I bought for a song, mahogany sounds certainly different to rosewood, just as good in it's own way. Love it too.
Three years back, after a successful deal, bought a 0000-28H, five years old, from Elderly Instruments of Michigan.From USA to UK in 5 days, PERFECTLY packed, protected & wrapped. A friend of mine bought a D-28 about the same time,and it was also incredibly well packaged and delivery was prompt.
Love it too.
I play a Takamine Santa Fe EC-10 electro-acoustic for pub gigs and with the ceilidh band. It's fine.Ironically, it earns more money at the moment than the Martins. Stuff happens.

Elderly Instruments, gotta tell you - Their postal service is so good that I'm telling you all this in case you have any hesitation about buying from them. I love it when you can recommend a firm from several deliveries ( I bought other things over the years ). They are good. They are reliable.
No, I don't work for them.
