Please note that we have adjusted our prices on all of the Hammond Manufacturing products.  On May 19th, 2008, Hammond adjusted the prices on all of their products for the 3rd time since the Radio Daze Catalog 306 was published.  We held our pricing until this most recent increase. We feel that you will still find our new prices to be very competitive.
