I have used the Cookstart 15 piece set.  This is a nice little starter set or if you are making smaller meals or sides.  I love the non-stick.  So, it is easy to clean.  I think my favorite piece is the pot with the strainer lid.  So handy when doing pastas.  I love that it comes with a utensil set with just about all the utensils you would need to use.  This will be handy when making smaller meals.  You could not use this for huge meals that you would want to do as the pans, pots, etc. are smaller.  My 12 yr. old son loves this though and starting using the set as he is taking a cooking class this year and is experimenting at home.  This is perfect because he is not making huge portions.  I would recommend the set.  This again would be a great starter set for someone.
