Welcome back..... also from Michigan. It's good to hear that you have some vintage machines. Check out the vintage group here. We love all our sewing ladies and tinker with them all the time. I don't have a 201 yet but am looking for one. I do have a 127, 15-91, 101, 99, 4 FWs, 3 Vikings, and elna .... oh, and a hand crank that I haven't cleaned up yet. I love and use my vintage machines more than the fancy expensive one that I bought 12 or so years ago.
As far as equipment, it sounds like you're ready with the basics. I also would suggest a 60mm cutter to use with your new larger mat. I find that I use the 60mm most.... it doesn't get dull as fast due to the larger size and I can cut through several layers if I choose.
Happy Quilting!
