Hey - good for you Mark! I think the Doran and the one you ordered are exactly the same. I've been pleased with the Doran unit, although I have heard of some cases where the sender doesn't fit the hole or opening in the wheel.
It is a pain to screw and unscrew the sender on the valve stem that faces inward - I resorted to laying on the ground and reaching my arm inside of the duals. I'm used to that process now so it doesn't seem like a huge deal anymore.
You got the high-dollar desk
with the power port. Mine is the plain version.
Good luck on the install and we will look forward to a few pictures!
