From experience, false economy, unless you can pick one up for a low price. Unless you know what the insides are like and if it will calibrate, you could be buying just an empty case.
A new dial face often needs also a corresponding new movement.
We are one of the companies that have made up new 4" eccentric pressure gauges and have invested in new movements as well as the brass internal and external bezels to make up a faithful new gauge. Equally, if you can find an old case with a solid back and unmolested bezels, although these we can replace, this would be your best and lowest cost option. Believe me, don't shy away from what may appear to be an expense, it may end up your cheapest option if what you want is an authentic looking eccentric gauge. A good old case and bezel with nice beveled glass rebuilt with a new movement and dial face is for me the best option, if you can find an acceptable old brass case.
