Many BD domains are overpriced IMHO. Guess they have a "we can hold 'em 'til they rot" attitude since the are not inclined to seriously negotiate. Lately they've been improving their "domain name as search page trigger" function. Still too damned many pop-ups for my likes....but I've seen worse. Truth likely is that a growing prevalence of multi-pop-up generating domains will kill the "type in the domain name as search" business model. Nothing like self-interest (greed?) to ruin a good thing.
Little BD secret: Sometimes, when digging around in their domain bins, you can turn up a domain they haven't yet overpriced ;-) I've snagged a few that...ahem, cough....I'd say were actually bargains. Maybe after 250,000 domains they are losing track of a few. (I'm a fool. Don't take my word. Do your own digging.)
Darn. I hate giving away little (hard earned) secrets.
