Grease Gun (ordinary manual sort)

[Bravheart]

The type that takes the screw in cartridges are the quickest, easiest and cleanest to change. I've got a speedy grease two handed gun and has a lubeshuttle adapter to take the larger threaded cartridges. If you want to stick with manual these are the business, no plungers or springs to faff about with. McNaught are well though off as a regular gun but never tried one.

Got a lubeshuttle one had it for several years got it from eBay with the cartridges as a deal works perfectly every time grease cartridges are super easy to change as well.

Speedygrease £60 or so and can be used one handed

Then another 20 quid for a decent lock on end

Next step up I'd say would be a milwaukee battery onebut 250 quid with a good lock on coupler and a battery!
