For anyone looking for a used Bernina coverstitch machine (same model as Juki MCS1500) you may like to know there's currently one on ebay
here . It concludes Monday 21:24, not a lot of useful information from the seller so you may want to ask them precisely what it includes.
It's the model I bought about a year ago and it's been wonderful - very well behaved and not as fussy as many of the others seem to be (Juki excluded
).
