This will be my first guitar but would like it to last me a very long time. The main purpose of the guitar is to be an acoustic for playing in my room but would still like the feature of plugging into an amp.

Can anyone recommend me a good used acoustic electric under the $200 mark?
no but I can recommend you the Search Bar..... and how are we gonna recommend you a used one?
How about you just be nice and recommend me a nice acoustic electric under $200, I am well aware of the search feature. No need to point that out.
