I am making up plans now to re-enter the hobby by building my own tank and stand, but wanted to check to see if someone local had a tank similar to what I am looking for and were willing to sell. Basically, looking for anywhere from 36"x36x16" to 42"x42"x20" to 36"/42"/48"x48"x20" -- glass or acrylic. Center overflow preferable, but corner or center fine. Or non-tempered bottom so can drill myself. This is a months-long project, so not in a hurry. Thanks.
