I would suggest raising your budget just a little bit if you possibly can. Yamaha, for example, makes a wonderful acoustic guitar for $200 that would do you well for a number of years. Other suggestion would be to look at Epiphone as they sell some intrductory kits for both acoustic and electric guitars that include everything you need to get started for around $250-$300. It even includes the amplifier in the case of electric guitar, tuner, picks, a beginner book, everything to get you started.
