Help me pick out my first guitar?

No!!! You were making the right decision before with the solid top Yamaha. If by music store you mean Guitar Center or some big retailer like that, never listen to those guys. They are salesmen, not musicians. And by the way, although this will surely get me some thumbs down, you are getting some very uninformed advice here. Trust me, get the Yamaha.

I'm doing the same thing right now. The best thin to do is to get one of those 100 dollor starter kits. NO FIRST ACT CRAP!! Epiphone is great. Then as you get better, get an accoustic/Electric guitar so you have the quality if ab acoustic and you can plug it into an amp later. But wait 2 years befor upgrading. So go with the starter kit, the upgrade "upgrade guitar only!!" then get better and better.

first act crap is the junk you basically find at a walmart store or a really cheap guitar. yamahas are a decent beginner guitar but takamines sound qaulity is amazing..personally id go with the takamine

Get a cheap epiphone or squire, the cheapest they have and a decent amp. Do not spend a ton of money on a guitar only to be left with pennies for the amp. Remember, a cheap guitar can sound great on a great amp, no guitar can sound good on a crappy amp. The amp should definitely be your main investment.

I bought the Squier and it's still works fine after 7 months of daily use. And it's only 100 dollars or so. Although, I will get a Martin when I get the money of course.

Well, sometimes you need to go with instinct.

Definitely get the squier if you can't decide. Fender everything's the best.

I'd suggest getting a cheap guitar your comfortable with playing just to learn on, then upgrade later on.

Fender for sure it is very comfortable to play and sounds great

you should probably get the squire. epophones in my experience go out of tune very easily. squiers don't so much.
