Best DIY reservoir?

Let's do this RIU...

I need a Food grade plastic 32 or 55 gallon container with lid.

I see them selling for around $100 in the local hydro shops. I'm just wondering if anyone has found a cheaper diy alternative.

Not an issue for some but when you're setting up 4-6 reseviors, using every dollar wisely counts.

I'm sure lots of people could benefit from this information. Please share your knowledge!
