Case is really nice as it has the bracket in the lid to hold the foot controller.
edit - I paid less than $600 for this but will have a little over $650 in it by the time it's ready to ship back east.
I put an LED light in it, new belt, new feet on the machine, the foot controller feet were good to go as is, lubed it up and oiled it, new felt drip pad too.
Based on what I've seen on the GW site and on the Featherweight site, I'd value this at $1200 easily now.
