it's the same anywhere, even on gfy, people can ask all they want, whether someone is willing to pay is likely a big different story
there are good deals around too, but you are right that some people are completely unrealistic
I was bidding on a cheap domain a while back and stopped bidding at $140 or something, the domain ended up selling for $160, and a month or so later I saw it up for sale and the dude was asking $3000
play around with the filters and sort functions on those sites and you can narrow down better what you are looking for, I like to look at the domains in auctions that are getting close to closing and you can see where the action is and jump in if you want
