Hello im looking to buy new acoustic or acoustic/electric guitar in about 300-500 max 600$ price range, cause im no longer satisfied with my 1st guitar after 8 years of playing.

My 1st picks are :

Fender CD 140 SCE,
EG333C-LTD takamine
EG340C takamine
Seagull s6
Martin DX1

Pls tell me your thoughts about these guitars and if you have some more guitars on your mind, pls share your opinion with me, ty
I'm not so much of an expert, but I have good experiences with my Cort mr710. Might be worth taking a look at. I mainly use it for fingerpicking though.
