Not to say I'm an expert or anything but I do have a good sense of value and will give you my honest opinion and some ideas. If you want an appriase post the name here and any other related information.
Hmm ok sure can you tell me how much you believe these domains are worth:
Sa.Vc - Due to the unknown extension it would be hard to sell and not sure how much it costs to register that one. Same with your MySpace domain. Market this name for $xxx at least due to LL.ext being so rare.
MySpace.hn - Never heard of this extension either which is not much of a plus. Great keyword but low paying PPC wise. I would try to build this into a resource site or sell of to an owner looking for one. Obvious TM issues and MySpace has sent C&D letters to people before which hurts a sale. End user $xxx, resale mid $xx unless it gets good traffic, IMO.
