The large air tables were quite expensive, but can be found really cheap second hand because at over 400 lbs. you can't ship them. Even if the air isolation doesn't interest you, they can be a great stereo stand and really helped every turntable I have heard on them. I think the top shelf alone is over 300 lbs. and quite inert. I don't have my WTL turntable anymore, but I think all of us vinyl junkies fight the same gremlins.
