I am trying to decide if this small electric impact would be a more useful tool vs. getting an electric ratchet. http://www.makitatools.com/en-us/Modules/Tools/ToolDetails.aspx?Name=WT01W I'm leaning towards this Makita 3/8 inch impact since it would be better at removing fasteners. This would be mainly used for doing work on my personal vehicles to save time. It seems to be getting very good reviews and wondered if anyone has used anything like this. I don't have air tools and have never used an impact wrench before.
