Decent Air-Powered Grease Pump, Trolley Sold Separately

This air-powered grease pump is a solid option, better than cheaper alternatives but possibly not worth the full price. It is a rebrand of an Australian model. Pressure is strong, setup is easy, and it primes without trouble, performing as well as cordless grease guns. The hose and handle are heavy duty. Note that the roll-around trolley is not included and costs extra; a plastic trolley sized exactly for a 5-gallon bucket works better, as the larger pictured trolley holds the bucket poorly.
