Fuel flow meter

My navman has officially quite on me. Does anyone have a recommendation for a good stand alone fuel flow meter that won’t break the bank? Going to a single ox66 225

Lowrance makes one that I put on my boat 5 years ago. LMF-200. $169 You can hook it to a Lowrance Net and take a GPS feed from your chart plotter to give you mpg… as well as flow rate and fuel remaining.
