Reubent:
I've read the spec's you mentioned, but forget the model #.
There were 2-3, maybe more, models housed in what seems to be the same case as the SD-EX111.
I purchased extras, spares for my parents and our unit, but the ones in use have been completely reliable for the past 20 months.
Tried the inexpensive ($39) SI and found it to sound odd/funky, with both battery and wall wart power.
Each to their own.
