I bit the bullet and ordered a WB68 off of Ebay a couple days ago, it's about $30 including the shipping.
I figured since the post office strike is just rotating right now, I should be pretty safe.
I'm planning to mount it under the sundeck (which is directly below the dish), so it should be dry as a bone there.
Thanks for the help everyone.
Please come back and advise how this switch works for you.
