I have been researching electric cordless grease gun. I have always used a manual one. I now have an excavator and have a need for one now. It seems Milwaukee,Dewalt and Lincoln are most popular.I wish Ridgid tools made one since I have a 5 piece lithiun set already. The cost should remain $200 and under. My research shows the Milwaukee 12v seems to be the best bargain for about $165 for the kit on ebay. What are you using?
