Ive been on thia topic for a few weeks...power wise the two tops guns are the m18 fuel 200ft lbs and snap on 230ft lbs... I decided on monday and bought the 3/8 m18 fuel... Great power smaller and lighter then the snap on gun, oh yeah and warranty is better. I ordered the 3/8 and circular saw bare tools and got the free 4.0 battery... Thats saled ended the 28th tho
