Product review (5 stars): If you don't have this already why are you still reading this?
Numbers so big my parents can read them.  They even understand them.  They even managed to install it themselves.  This is probably the best basic wireless in/out thermometer I've ever seen all joking aside.  If you don't want to spend the money on the home weather station this is the exact level of involvement for you.  You'll find you like it so much you spring for the full weather station after you've changed the batteries twice because you want to know more.
