Those look cool.. I'll have to get my hands on some for my two boys this year. Got them an air rifle to practice with in the back yard and want to take them to the range this summer with my Remington 597 or Ruger 77/22.
I've got a 702 Plinkster for my kids as well, and the daughter has her own bolt action Savage very similar to the pink one you had. Kids LOVE to shoot.
I bought my plinkster new and have never had a problem with it, it's not even picky with ammo.
