Congrats! I think the pink made it worth getting, and I'll bet you'll have it in working order soon. I wouldn't be surprised if the legs and foot pedal turn up at that house before they're all cleared out. You might offer to sweeten the deal if she'll notify you if/when they do. A likely scenario was that there was a move and the movers took the legs off to prevent them from getting broken. If that's the case, the chances are good that the machine is in working order because who would have moved it otherwise? The rest of the stuff was probably packed in a box, and it could all show up or maybe not.
I have seen a similar machine on our local CL not too long ago, and they probably turn up pretty regularly, so maybe the solution is to try to find a second one that has the foot pedal. It might be cheaper than buying a pedal separately!
