If the price is any sort of decent at all, Grab it. Don't ask me what a decent price is, BC prices can be far different than here even though we share a border.
Singer 201s were Singer's top domestic model and were also used in commercial and light industrial settings. They're very well made and are great machines. They use a gear driven full rotary hook. It's a very strong design. That one appears to be in great shape. The bentwood case makes it even better IMO.
The model 15 behind it should be a good machine too and may have a slight edge on the 201 for FMQ.
