I have encountered the information somewhere that the lectins can be cooked out of legumes with a pressure cooker. We really need beans in our budget! Any idea how long one would cook them to accomplish this?

It varies by bean type, and altitude. Some beans call for more extensive (longer time) treatment (see Tikivana and others above), Generally it is: clean&rinse, soak&rinse, pressure cook, ferment (if applicable). To speed phytate removal soak beans/etc with a tablespoon of rye or wheat included. Also consider just removing the "worst actors" like soybeans, or by picking lower lectin types.
