Let's take a look at the difference between the Siemon's 66 block and the Dynacom 66 block. As you can see, they are both very similar. Besides a slight color difference and hinge mounting points, they are practically the same block. We do prefer the Dynacom block because it's priced better and includes a clear cover at no additional cost. Both blocks are available at http://www.Discount-Low-Voltage.com/
I like products made by Suttle Apparatus. Their 66 blocks have a very solid feel to them and are built just like the ones made by Western Electric. Come to think about it, Suttle's blocks were sometimes rebadged & used by the RBOCs.
