Don't buy Indian or Chinese guita
I bought an Indian guitar sometime ago and bought a F310 as well. F310 is far better. Buy a Yamaha one and you won't regret.
They usually have seasonal offers during December and April and give a good discount. If you could wait it will be a good deal.
I saw somewhere if you buy Yamaha instruments through your music instructor, they give a discount too.
Other option would be to buy a second hand guitar.
I guess C40 guitar mentioned in a previous comment is a classical guitar.
Also, you could get a mic and pre-amp fixed to your guitar from a person in Kesbewa area. If someone need, I can find the contact details.
