Wanted: Looking for a kids bow for my 7 yr old grandson

My 7yr old grandson is enthused about archery and to date we have played with an inexpensive child's traditional bow and then a child's compound bow, both of which he has outgrown. Now it is time to upgrade to something with sights etc that he can start to properly aim and shoot with.  Looking for something that somebody's kid has outgrown or gone away from shooting. Let me know what you have please.  (Calgary area)
