It sends the wrong message. With a company, you want to be optimistic, and the domain they use should reflect that. Example: yes.biz vs. maybe.biz
"Do you offer quality service?
YES!
"Do you guarantee your work?"
YES!
"Will you provide me with reliable support?"
YES!
Or...
"Do you offer quality service?
Maybe.
"Do you guarantee your work?"
Maybe.
"Will you provide me with reliable support?"
Maybe.
I think you see why this domain might do well at a $15-30 area.
