im no silverline fan tbh, not that i have any of it, i know their stuff got dearer and one could only hope the quality went the same way..A few years ago I bought a Silver line air nailer https://www.toolstation.com/silverline-air-framing-nailer/p23494 it's not exactly refined, but it fairly whacks the nails in & pretty much every nail has gone fully home - even 90mm ones into tough timber.
its an option for the money, if i wore it out id have reason to splash out, doubt that id happen tho.
bought a milwaukee m18 vacuum cleaner last week, and a stihl kombi engine the other day, maybe best curtail the spending for a bit.
