I Need To Purchase a Guitar

My guitar was destroyed on a recent flight (1969 Marcelino Barbero) - I'll spare y'all the details. Suffice to say, the airline finally agreed to compensate me for the loss, and in mid-July, I head to Madrid. This would seem to be the perfect place to buy a guitar. My concern is that I haven't bought one since, well, ever. The guitar that was destroyed was a gift to me by a dear family friend in the early 1980s. I am looking for advice as to how to go about purchasing a new one. Does anyone have any suggestions as to Spanish luthiers, especially in Madrid? Anything in particular I should be looking for? Aware of?
