well i use a 5 gal. bubble bucket and a 28qt. rubbermaid bubbler

i keep 2-12 inch air stones in each and love it

but ive used NFT before and have taken a real liking to those also....
if you understand the concept of NFT you can make one easy with some PVC pipe and a rubbermaid container and a water pump

hope it helps....

later buddy!!! =)
