For those who might be interested, I have my SDS100 set up and running in my office. I'm off of 79 more or less on the RR/Hutto line.
The SDS with the Remtronix 700/800 rubber duckie gets the Austin, Pflugerville, and Williamson County and Bastrop campuses without difficulty. OTOH, I have my trusty 536HP set up in another room with a back of set antenna and am receiving only sporadically. My guess is that some of that is the antenna and some of it might be simulcast distortion. The 536HP might be going up for sale if it turns out not to be adequate for my needs. I have a Remtronix 842 and a right angle adapter and will see if that improves reception on the 536HP.
