Guaranteed way to delight your grandchild (or child).  We put up last spring and it still looks brand new, after having weathered a Montana winter.  
Labor intensive to put the swing set together, but so worth it.   Do make sure you anchor the swing set securely if you have ANY wind, as we have had it topple more than once, we have since cemented the legs into the ground as the grounding pegs are not sufficient for keeping the swing set from blowing over with big winds.
