Here's my list:
The most modern machine I have and use every day is my Viking Lily 545. Bought it used off of Ebay and love it. Before that I used exclusively my two-toned Singer 301 in a table. Very reliable machine. I have five Singer 301s, one Singer 201, five Singer Featherweights, including a white one, a Babyloc from the '70s, A Kenmore from the '70s, three treadles and three children's Singers. Too many machines! Need to sell some of the Singers. Neither of my daughters sew, so I guess I'm holding onto them for nothing.
