RCBS "The Grand", what's it worth

[rattlesnake]

I bought this 20 ga. shotshell progressive press when my kids were shooting skeet and used it to relaod 1 box of shells then took it off the bench and put it back into the box to never be used again.  What do you think it would be worth and where do I list it for sale or trade on GBO?

My rule of thumb for selling stuff on Craigs list is to ask about 2/3 what the price of a new item costs.
