I have two sanders-a Performax 16-32, made during the Jet transition and a General International (no comments about the General, since this is not a thread about that style of sander). My 16-32 has been a great machine. I have the table extensions on it it (no issues). I also have the magnetic ceramic guides that keep the drive belt running true. I have no issues changing sandpaper, but I also have the optional changing tool that makes it easy-Peasy.
