Totally agree, but don't panic if you see that people are willing to pay even less, like occurs at namepros.
i'd say same, not much unless you can cleverly brand it, like 100k.com as an example -- make like 100k - 100 thousand reasons to visit something, iono, something like that, just an example
nothing is worth nothing that means everything is worth something who cares if there are so many 4 char domains out there, when ur looking for one, u'll never find one, its part of life, what u look for is never there, u find it when ur not looking for it lol
