Would I use them to sell? Maybe. Would I use them to buy? Most definitely. As mentioned further down in this thread, buyer's agents have every incentive for the buyer to pay as high a price as possible (due to RE commission structure). I want someone earning a fee on my transaction because they got me the best price (as either buyer or seller).
Price of a service can be a form of signaling, but paying more for something does in no way mean you're getting better served.
