Best barrel drums for Flatbed (Similar to the original paint drums)?

[MrNormalDraws]

So I got two of the original flatbeds with the paint drums, but the problem is that the last one I got had some scrapes on the barrels and I can't find another one without spending almost my wallet. So I wanna ask anybody if there's any decent barrel drums I can find online, on any site?

I tried looking at shapeways, but I don't know if any of them are small like the original barrels. I know that the load has 3X9 barrels and 2X6 barrels. If anybody can help me, let me know.
