I need a regulator for air tools. I have a 3 stage setup for air fed, but i dont want to whack loads of rubbish though those filters, and its easier to buy another regulator than mess about teeing off. So, do i buy a cheapo, or a branded. Is there really any difference? Eg - https://www.toolstation.com/air-filter-regulator/p26616 or, for double the money - https://www.ebay.co.uk/itm/Metalwor...903314?hash=item1a29a62252:g:dGMAAOSw4CFY7cEu Or, if you want to go to china, pocket change - https://www.ebay.co.uk/itm/1-4-Air-...913201?hash=item44341a45f1:g:jgIAAOSwO2lbdWY4 Tools will be things like, DA sander, rivet gun, mastic gun, etc. Thank you.
