Skarpi, my advice would follow Little Hawk's exactly. Every guitar is different and what suits one person may not suit another.

To me, the most important things are (1) sound production and (2) ease of playing, followed perhaps by looks. The name means very little - Martin or otherwise. I like Lowden guitars, but I've tried three or four in a store and every one was different. One really appealed and I was tempted to buy - the others weren't of value to me at the price being asked.

Have you considered having one made for you? For the asking price of some factory, production-line Martins, you could commission your own custom guitar from a decent luthier. Just a thought...
