I guess I just need to get a couple 5 gal. buckets.
It is going to be hard to do better than a 5 gal. bucket, whether plastic or steel. They are the ideal size/weight to be easy to move around, store (stackable) and transport.
Down sides: The pull up spout (as already mentioned, post #20) is the weak point. That poster blamed the "elements", and I suppose sunlight could be a factor, but they also "wear out" if you push them back flat and pull back out repeatedly. Which you have to do if you stack the buckets. 5 gal. paint buckets don't have this pull up spout, but are more prone to make a mess when emptying.
An add on spout like this, or
this (I have this one, but have only used it for paint) make the paint buckets more useful.
The 5 gal. cooking oil jugs have a bigger opening, and no spout, so the paint bucket spout won't fit. Also, when the outer cardboard box comes apart (wear & tear, or gets wet), the inner plastic liner is too thin to use alone. But a good option if you have a good source.
Currently I am using a 5 gal. tractor hyd oil bucket, but the pull up spout has cracked and started to leak. I plan to switch to a paint bucket, soon as I finish some house remodeling and have an empty bucket.
