Don't let your size determine the type of guitar you get. You might like a jumbo guitar, but you might not like the way it sounds and feels. Most "traditional" acoustics are a dreadnought. You really have to play them and see how they feel and sound though. You're right to look for a solid wood top, but you're not likely to get solid back and sides at that price. The top is the most important to the tone though.

Here's one you might want to look at:

This is a nice solid top guitar well below your budget, so you can spend the extra on lessons.

A Walden D550 is also a great option in your price range if you're not interested in Yamaha, although I personally think Yamaha makes great acoustic guitars for the money.

Crafter also makes nice guitars but they're a bit pricier and you won't find a good solid top one in your price range unless you find a used one.

There are a lot of options though, so you should go to a music store and try out various guitars to get an idea what size you like and what sounds good to you in your price range.

I would say Cremona or Honnor
