I am guessing $400, and yes, Solid Signal is the place to go as far as I know.
I would love such a unit! But overall I am happy with the gear that I have.
Would you view post# 40 in this thread and tell me if I used the second question mark correctly? Kinda puzzled me. BTW, if I get a 44, I'll only accept it if it is free of cost. I can wait until all the bugs are worked out.
