Sure, any chainsaw will clear trails or brush, but when your felling. Trees, bucking them, and sawing cord after cord of hardwood, those lower end saws will let you down.
If your just going to use it occasionally for light duty, but a cheapie. If you plan to use it a lot, get one that will last, or you will just pay less twice, rather than more once. You do get what you pay for.
