I just purchased an Alcor Model 204-18B Item #45993 last October. My original (alcor thru Cessna OEM) was beginning to give me intermittent readings on the rear so I changed the probe and still didn't solve it so I swapped the rear lead for the front lead on the gauge and it still had funny stuff going on on the rear. New gauge and it's fixed. The new one is a little nicer than the original. Has the user setting needles for reference purposes where the old original from 1968 did not have these. I purchased it through Aircraft Spruce and it was $490.95. I wanted the JPI or EI digital stuff but didn't want to commit to the big bucks for that part of the system at that time. Maybe someday.
