Like you I have a litany of stuff going back decades covered by an original Zerostat bought for $29.99 in about 1970, which is still going strong. It is white. I also have a newer blue one in another house that cost about $79.99. But both are relagated to back seat status these days by a Furutech destat III, which cost $399.00 and works so much better than the Zerostats that it isn't even funny. Progress marches on.
