If you generally shoot from a prone position or a bench, the bipod is the way to go. If you normally shoot from a sitting, kneeling, or standing position, then sticks seem to work the best, as they are easier to move or pivot if you need to.
Depending on your height, you can usually find some plastic or fiberglass poles (driveway markers or garden plant stakes) at a Farm & Home type store and get a bag of castration rings (usually packaged 100 for cheap) and slip a couple of the rings over the poles...a couple of lengths of surgical tubing or clear plastic gas line over the tops of the poles and you have an inexpensive set of sticks that can be cut to your personal shooting style and comfort... If you put a second length of tubing over one of the legs about 6 inches from the bottom, it will cut down the potential for them 'clacking' together while you are moving them or walking with them.
