In my old workplace we used the same 3M glue gun, using dedicated "ribbed" glue sticks.
They were available in many types, for different applications.
In 10 years it never failed, in contrast with other units, even of "blasoned" origin. Temperature was adjustable with a dip-switch, and you always had the correct temperature for the glue type.
It was a pleasure to use.
But, for a limited use in a home lab, I think it is too expensive, and "ribbed" glue is difficult to find (you have to order it, cannot find at a local dealer).
Don't know, it's up to the OP.
