Darlene, many, many years ago I picked up a 2-gallon aquarium for
$3.00 at a neighbor's yard sale. It remains one of my favorite
primaries for small batches. Over the years I've added 1.5= and
3-gallon aquariums to my equipment. A glass top would be nice, but my
wife made me muslin dust-covers with elastic bands and they work fine.
