Hi, I'm new here. I picked up a Singer 31-15 in great shape as a first machine to learn on. The clutch motor is a beast but tameable for me EXCEPT for those times I really need it to stop at a given point. Feathering it up was OK but down to a stop; not as easy. I bought the one Pinto shows above off Amazon.com for about $115US and $35 shipping to Canada. It arrived and the only surprise was there weren't any surprises! It installs easily in a couple hours. In my case the table already had speed nuts installed in addition the reverse configured bolt pattern. Even the belt lines up and works well. There is some fiddling with the 'speed control' knob. The light pressure on the pedal to release the brake and allow hand control with the hand wheel was welcome. I'd recommend you mount the on/off switch where you can easily SEE it because it's silent and easy to forget that you haven't turned it on! Overall, I'd say you can't go too far wrong for your money, except for your location! Good luck.
