Are these guys still around? Their website (http://www.sbsg-equipment.com) doesn't seem to work but google gives me this site: http://199.236.113.209/spabuilderssection/index.html although parts of it do not work either. Obviously my interest in related to the LX-20 unit that I can't find any info on. However, email to their support address (sbsg@sbsg-equipment.com) bounce back as: "Recipient address rejected: No such user".
