Thank you guys for all the answers! I'll try to find one that fits best for me. I think I am going to choose the Yamaha Pacifica 112V ($250/$300). It is not expensive and it seems to be a good one to start (I saw some youtube videos about it). I'll go to some stores to try this one and some others.

About the styles of music, I like pop, blues, r&b.. the cozy and calm songs (John Mayer and Mateus Asato - he is Brazilian and a huge inspiration, are my favorites guitarists at the moment.

Thank you for your time and if you have anything to add I'll be glad to hear.
