EazyBudget.com - A decent domain. I'm not a big fan of swapping Z's for S's but in this case it seems to work. It looks, and sounds like "Easy". EasyBudget...EazyBudget... yeah, it could work. I don't think it has a lot of value, the domain alone... perhaps $50-$250 depending on the buyer and situation. If you developed the name, got some traffic, and tried to brand the "Eazy"... it would certainly help.
2Leave.com - Not crazy about 2this and 4that names either, but this one is below average in my opinion. 2 Leave... 2Leave what? 2Leave your husband? 2Leave your job? It just doesn't seem to be a 'positive' image. But I'm sure there's a positive-spin out there somewhere. Not sure about value here. Personally, I would not pay more than $50-$75 if I saw it for sale here on the boards.
Need-U.com - "U" being used for "You" plus it's hyphenated. You'd think I would rip this name apart, right? Nope. I think it probably has as much potential as EazyBudget only because it's short, and "need-u" does flow pretty well (surprisingly). Somebody here at the forum will offer you $25-$75. Who knows what you might get from a developer looking for a unique name for branding, $100-$500? It definitely has potential for that. Then again, this name also screams BLOG, so it may never see a dollar.
Good luck in your ventures.
