In simple language, I am very new to all of this - Is the unit we bought and the update cord I received yesterday any good? Or have we thrown away our money? What are our options ( we gotone from Target at Christmas and another one from Amazon for a gift. I see where some of you are offering suggestions but the information is Greek to me, we are as green as you can get to this activity. Help,what a way to start LOL. It looks like a wonderful family activity to get our grand kids into, any suggestions will be greatly appreciated.
