You can pick up a very reasonably priced starter acoustic guitar - this will allow you to experiment and see if the guitar is for you before moving onto a more expensive instrument.
You can choose from a classical guitar, or acoustic guitar. The acoustic usually has a thinner neck and steel strings and the classical has nylon strings and a wider fret board. Both have their own unique sounds and advantages/disadvantages for a newbie. The best is to experiment and see which sounds suits you best.
I see many people that think learning the guitar is easy. When they discover the truth - that it requires a lot of dedication and motivation - they give up.
Having said that, there is nothing more satisfying than picking up an acoustic guitar and creating some lovely music. It really is nice to think that bit of wood and metal, in the right hands can create something sounding so beautiful.
It's worth the effort - good luck
