I don't know, if the guitar is good and will last a long time then maybe £100 max ?? Not sure how good that is for what I'm looking for. As for styles, I guess I'd like to be able to play background chords that voice can go with. Also perhaps some solo classical or jazzy finger plucking might be nice ? And, no, I don't really have anyone who I'm hoping to be like. I just want to be able to play the guitar really well with a professional instrument that sounds good.
Sorry if my answers are not as professional as you'd like. It's a new field for me so I'm a bit 'uneducated' when it comes to guitars.
