Cold Steel makes a variety of excellent machetes. They're light weight, hold an edge very well and have a comfortable grip. Those are three crucial features. As a teenager, I used a variety of machetes. The worst traits are:
1. Heavy ones
2. Excessively long/short blades
3. Dull or difficult to sharpen blades
4. Ones w/plastic, paneled grips
This last one is particularly important, and can rapidly make your life miserable. The area between the panels can, in short order, bring blisters sprouting up all over your palm and the web portion of your hand.
Cold Steel meets all my criteria for great machetes, plus they're cheap and tough. In fact, they're so cheap you can afford to take a number of different configurations.
Regardless of the kind you get, avoid heavy, stainless blades and grip guards.
