I have bought hard leather cases for all of my scanners except the newer ones (TRX-1). I am staying on top of this and any other 'sds100 case' threads and following closely, as a hard/soft leather case is a must-have for my future sds100. The case for the 436 looks like it will work with the current battery configuration, but when they come out with extended door and larger battery I wonder about dimensional problems.
phask - I have never bought a case from Uniden and do not remember them ever advertising any. In the past, I have bought most cases from Scannermaster, and a couple from West Mountain Radio. I'm sure once retailers have proper dimension information we will see cases advertised for the sds100. Would be nice if Remtronix would design an 'sds' version sma antenna that would work with this scanner as well.
EDIT: I stand corrected, Uniden does sell cases? Hope they are on the ball with the sds100!
