All crazy here ... I have only recently started collecting. Like a potato chip ... it started with one, and less than 2 years later I have 4 and I'm STILL looking (currently also watching hubby's PC right in front of me as he is searching for irons!).
One of the machines I purchased had good irons, a decent head that needed cleaning, and a cabinet that had decent drawers ... but the top is rotten. We sand blasted and repainted the irons, cleaned the drawers and we're going to fix a new top on it and we purchased an old coffin top to put over the head (instead of trying to build a top that will let the machine drop).
IOW ... the important part are the irons. If you have a complete set (and parts for those can even be found), with no cracks, then clean them up and work from there.
Go for it and good luck!!
