From my "research" today (instead of housecleaning), I don't think I can convert the 27-4 to electric because it doesn't have a motor bracket and my BF (he got it for me) really didn't want me to ruin the antiquity value of it either, so, that clears me to bring another machine into the house...LOL He loves old Singers too...LOL The 15-91 is really sounding like the way to go so far... I drove 15 miles today to look at one that was on Craigslist as Vintage "Swinger" Sewing Machine but I was so disappointed when she opened it up and it was a Touch and Sew...she looked at me like I was crazy when I told her it wasn't old enough...LOL I never asked her about the "Swinger" part but I would have really been cleaning that machine! :oops: :roll:
