snap on cordless 18v very powerful about $500 for set extra battery and quick charger. cheaper with ingersol and 18v just as powerful. I personally like hitachi smaller and just as strong but high price. Ive had all and sold the rest but the hitachi. snap on makes good stuff 99% of my tools are snap on, but air tools are definitely better with ingersol and cordless is either hitachi or milwaukee. I make my living with these tools and i have about $200k worth. so i know something about tools.
