Have you ever seen the Blue Press catalog? They offer one for
cleaning cartridge cases for $179.95 (12-1/2 quart bowl capacity), and a
smaller one for $129.95 (half that size).

I've looked at those, and as far as I can tell they're smaller. They look
like they might be better quality, but the bowls don't seem to be quite as
large. One of the ways I came across the Eastwood tumbler was from a
conversation with someone who reloaded 50BMG rounds. They had the largest
of tumblers available through any of the reloading outlets, and they felt
it still wasn't large enough. The Eastwood one looks to rectify that problem.
It is a pain that companies won't give the volume specs in equal units of
measure, but they do seem to frequently give the largest diameter of the bowl.
Since they're all round, and generally doughnut shaped, it seems fair to
compare them based on that measurement. Even when the diameter given is
the size of the opening and not that of the widest part of the bowl it seems
like it's still a fair way to do it, since the difference between the opening
and the sides rarely seems to be so different as to create a real calculation
problem. Besides, if the opening is that much different than the sides of
the bowl, how is that good design? It still restricts the size of the parts
I can get into it.

There are some good sized ones available through Rio Grande (some are listed
as 20" with around a 6 gallon capacity), but of course they carry the Rio
Grande price tags. Truthfully, as Gunner as suggested, the best option for me
as I want one that's both large and cheap is to build my own, but I just don't
know what the hell I'm doing enough to build one without some sort of plans or
more solid background with the devices.
