K2 fitness
I ordered a 16kg from here and I like it better than Dragon Door's. If you want a dragon door kettlebell go to the forum at dragondoor.com or google and search for an RKC instructor in your area. They get them in bulk and sell them sometimes. I did this and got my 1.5 pood KB for $100 no shipping.
For OP I would reccomend doing Enter the kettlebell. If you stick to the program you will see great results.
