Work hard and save up and buy a quality complete bike. Obviously, the best deals are used, but you have to luck up and find a bike that fits, has the features you want, the price you want in your area.
The sure bet is to buy a new bike. The best way is to buy from a shop where you can be guaranteed that it will fit and you like the way it rides. You can't get that buying online. Buying online is great if you know EXACTLY what you want. There are more bad choices than good ones for bike noobs.
The good thing is that the summer is over soon. That means that shops will have lots of sales, soon. Winter is a great time to buy a bike. Shops are slow and prices are low.
