This one is slightly bigger and heavier but can also store stuff in it like coils you have made or a container for spare screws. The two cheapest ones have the same mandrel sizes.

Thanks for the info. My problem is that I like the idea of how sturdy this one seems to be and the lack of hard edges but the cheaper aluminum one would probably be easier on my hands due to being lightweight. Having carpal tunnel syndrome makes choices like this both hard and very annoying.
