just ordered 3 of the dwyer gauges. ill post back and let anyone interested know what i get.
i 2nd the black hipac gauge, i think i might been one of the first to swap out a disco gauge on a disco i doubt it tho... neways mines only about 50 psi off from what my hand pump was reading but havent checked it against my tank yet. but we all know the benjamin handpump probably had a cheap gauge in it.. the black hipac is 15 not sure if thats with shipping or with out shipping. i think it will work with the mrod..hopefully it can be used on a mrod
my comment was based off since i have been a member i hadnt seen anyone else swap out the gauges. maybe people did and hadnt posted about it idk
