Hi Allen,
I found mine at Bloom's in the Fair Lakes shopping mall. (End corner past Wal-Mart in the parking lot)
Beer aisle, Miller Lite section on the left side. I got the last one on the shelf last week. Big conversation piece in line. I think they sell out fast. $18 Pretty good, you do get a lot of foamy head and can't adjust the pressure, but after about a minute it all settles down. I'd buy it again instead of a case.
