I was helping my friend choose his first guitar a while back, we were trying out guitars around peninsular/excelsior, and I was really impressed by the tanglewood guitar at TYMC. I can't remember which model exactly, but i think its a solid cedar top, dreadnought guitar without pickups and cutaway, satin finish, and its somewhere around 300 or less with a gigbag. Its hard to beat for its price, it looks great, feels great, sounds great, and good workmanship. Its well setup and TYMC offers a free setup within the next 6 months after purchase, bang for buck!
300-400 will get you pretty decent guitars. You would like to try guitars at luthermusic also, the people are nice and they actually pay attention to what you are looking for, they have a nice collection and their guitars are well setup.
You can also try Yamaha, they are really well made for its price.
The above are just my humble opinion though, have fun trying out.
