Emodels.com - Quite good, as could relate to fashion models or toy models. However, in some ways not that brandable because it's a bit "generic".
Impex.com - Nice because it's a 5 letter .com. Is it free from existing intellectual property restrictions? I wouldn't be surprised if there were already companies out there with this name.
Re value, yes there is some potential here, but value is whatever firm offers you get.
