Unless you have a digital gauge on the dash your gauge cost thirteen cents. According to experience with my factory temperature gauge if it ever went to "H" the engine would be around 2,000 C
Dollar for dollar nothing can touch the cost, ease of installation and fuel cost of a Harbor Freight 2-cycle engine and a Megawatt 36-amp charger. Not even close. Don't bother to compare. Not good for campgrounds with generator bans or national parks where employees pray for an outbreak of Lyme disease because their pay does not change whether there is a thousand campers or zero.
