Dave, try the bakery counter at your local grocery store for 5-gal buckets. Some will give them away for free, others might charge $1. They aren't as UV-stable as the black nursery pots (they will get brittle after a year or two in the sun) but depending on your need. they can be more versatile- control how big your drainage holes should be, or set one inside another to create a self-watering pot. I prefer them for plants that come indoors in the winter as they are easier to keep clean, and sometimes the handle is convenient too.
