Your hands are the same size as mine and I already play guitar for 50 years, lead and rhythm so don't worry about that. Where in Thailand do you live, I live just south of Hua Hin. There is a Yamaha store nearby that sells some cheaper brands to and with good advice and if you look on Amazon you might be amazed how little you pay for transport and import fees are included in that prize, I buy stuff on Amazon USA for not even the half of the price what it costs here.
