Fiberboard drum source? How about a plastioc barrel?

[skillington]

Has anyone found a reasonable source for thirty gallon fiberboard drums?  In terms of weight and convenience fiberboard seems like the way to go, but not at over a hundred bucks. 
I've found a source for 30 gallon plastic beverage barrels for about fifty bucks, including shipping.  They appear to be strong enough to withstand collapsing from vacuum pressure, and would be lightweight and easy to work with.  Does anyone see a serious downside here? 
I expect some will express concern about static electricity build-up, but I've seen that claim debunked, and the barrel could always be fitted with a ground wire, anyway.

if you want a box for free, then go to any welding shop and they should be able to give you a 1/8" thick, about 24" in diameter canister that holds their welding wire spool.  it has a latching top, so it will seal perfect and you can have the inlet in the side or the top, it will be easy both ways.

Thanks for the tip - I'll give that a try.
