I got mine on ebay last summer and it was just over £300 - probably cheaper because it was a Kilbowie one, with a higher voltage motor, so I wasn't bidding against US bidders.
I was thrilled to bits, as it sews much nicer than my white 221 which seems sluggish compared to my 222K - also the feed dogs drop on the 222's, so you can FMQ on them too.
