The Singer 237 Fashionmate is not a 'luxurious' machine - and it's the tan or ivory that replaced the black - and it's a heavy thing (over 30 pounds - I think) - but it sews nicely - and it does a very nice satin stitch.
You might need to get it cleaned, oiled and adjusted - or do it yourself - AND I can sew almost a 'perfect' 1/4 inch seam with the 'all-purpose' presser foot that came with it.
The one thing I can think of that really annoys me about it - the thread spindle - it looks like a birthday cake candle - and is about as sturdy. What was Singer thinking with that thing?
