I was 3rd user of my 558C. Although it was not the most ergonomic handheld I got, it has surely the best sensitivity, the less intermodulation, the best audio I encountered. It could also be used as a cross-band relay, which was space-age feature in 1993. (it was also the most expensive HT that time). Its main problem is it is a physically delicate radio, with tiny buttons.
If you find one unused or in good condition, I think it can still worth about 200 dollars.
