Killer Deal!!
Congrats!
I have the FG700S as well bought used for around $125. maybe $140 with shipping.
"The Internet" says that is one of the best beginner / budget acoustic choices out there 5 or so years ago.
Mine played fine once I adjusted the truss rod back then.
Once I became more proficient working on guitars I dialed the nut slots in and sanded the saddle to bring the action a little lower.
Still high compared to electric - but where it is "supposed" to be from what I read.
Really easy playing, good sounding acoustic for short dough.
