Cleaning it yourself is no problem, but I'd check the electrics carefully on a machine that age. I just purchased a Universal from the 50s and some of the wiring underneath is very brittle. $35 is about right for a machine in this area without a cabinet, but the price on vintage machines is, "What is it worth to you?" If it's a 27, does it have the Sphinx decals. They are so pretty. The vintage metal machines are worth purchasing. FWs are as cute as can be, but I like my homely 301 for sewing.
