I use a Doskocill ACCESSORY CASE for a hard case for my Contenders. There is enough room for a Complete Super 14 Contender, extra barrel(s) and some extras. I do not remember the exact dimensions (I'd have to go measure it to be sure) nor the price but I think it was like $55.00.
I have heard of some guys using a spotting scope case to carry their Contenders in but have never done this myself. For a soft sided case I just purchased a couple from Ace Case and am totally pleased with them for the price.
