Agreed, the SW100S would fail on the "rugged build" factor, as would
the SW07. Bob will need to prioritize from among these various
criteria, since he can't have it all...

Before acquiring the SW07, I used to carry a 606A around quite
frequently. It's a reasonably priced radio with decent performance,
although it's a tad larger (5 3/4 x 3 1/2 x 1 1/4) than what Bob is
looking for and, as noted by David, lacking in SSB.
