DA Aquamaster:You just cost me $180.00 and have given me a good reason to switch from my DW Mistral to one of my DA Aquamasters.
I am glad to hear that you are getting one.
I hope you are getting a reproduction silicon diaphragm. I am amazed at the difference they make.
Another major convenience item are Bryans reproduction main body ring clamps. I added captive nuts to all of mine (rivet nuts, from McMaster Carr) and I use a thumb screw, which adds a huge convenience factor.
Good luck
