Whilst not the cheapest or biggest capacity I've ever seen it is both affordable and available. Aldi have done cheaper but are random availablity. TBH I think a stainless media tumbler does a better job on brass.

Also Anemometer (Wind Speed) for only $14 while stocks last. May be useful for comparing actual wind speed to flags/mirage.
