People very often need guidance about guitars for beginners, the best thing in a big city is to ask the teacher what sort of instrument would be best and perhaps to visit a large instrument store with a teacher or experienced player who knows what to look for. Somewhere like the Spanish Guitar Centre will advise and allow you to try instruments under supervision. If you live somewhere other than a big city the choice may be more limited. It is worth checking out some of these links for prices and specifications before visiting a store. I have had good experiences with buying online, but please be careful to read the small print.
This page carries links to Amazon in the UK and to pages that feature Amazon USA. It is not a guitar shop however and while we are happy to advise we do not take responsibility for supplying or selling instruments!
