Very nice domain. I would high $xxx (it's not so prounouncable ( but I'm not native english speaker so I don't know but prounounce it like teau) but still ends with O which is great).
Nice pronounceable name ending in "OO". As far as I know "tioo" is not a spanish word but "tio" is, it means uncle. I would also value it as high xxx to a reseller.
