Keep on the lookout in western Canada.I imagine there will be some good deals out there due to the drought.A good place to look for private sales is www.producer.com
just read an ad in the agonline (successful farming) 'classifieds' website-click on the implements link..a guy had two like your looking for. Wouldn't give a price, and I know why since they bring anywhere from 25 to 35 at a sale. Good luck.. GS
I live in central WA the local Deere dealer in Quincy has a CTS that is in excellent condition and only used to cut wheat. I dont know the price but since this is not the common model they will probably make a killer deal.
