Afternic recently began offering Dan.com-lookalike landing pages with GoDaddy branding. I liked them enough to move inventory to them away from Dan.com. Afternic followed this up with the ability to allow prospects to make an offer to buy a domain name in addition to the BIN and LTO options.
Unlike how the Make Offer process works on Dan.com, there is no negotiation box for sellers to communicate with buyers directly. Instead, when a buyer submits an offer via the landing page, the negotiation is handled by a GoDaddy broker.
