T&T: A radar question

[Jim Slocomb]

Lo all,
I'm contemplating replacing an ancient and failing furuno (repair parts no
longer available) with a new radar.
 
I would be interested in what the list thinks the good units are. I'm not
interested in the integrated, network based units. I would like the
reliability of my old furuno, a good narrow beam width, marpa or arpa, a
1/8th mile range, all in a stand alone commercial/industrial grade small
boat radar.
 
TIA,
