Have you tried "Smart Pots"?
smart pots - Google Product Search

Basically its a bag, but made from stuff like the "weed blocker" fabric you put under rockscaping or mulch in your garden. It breathes really well,... too well in some peoples opinion,...(great for heavy soils) my blueberry is in a 3 gallon smart pot,... needs about 1.5 gallons every 2-3 days.
