Be advised, that currently the seller for the K-2006 below in the Amazon link is NOT Amato Industries which is the only seller we recommend buying from. Some other sellers are substituting the K-2005 which you do NOT want. However, Amato is the seller for the K-2006C which is the same kit as the 2006 but just with larger bottles of some of the most frequently used reagents. (Hopefully, Amato will restock the 2006 soon for those people who do not want to ahead and get the 2006C.)
