Used radar
If it works, then, there's your answer. A lot of times, new gear like that comes out and folks trade up, so used doesn't necessarily mean "wore out."And, that $1,400 price; does that include the radome? Most times, radars are sold as separate components because some people want 16 miles of range while others want 24 miles and that depends on the size of the radome and the power output. Sometimes radomes are as much as the display units. Just a thought.
