recommendations for electric impact- light use and best price

That's why I went with Ridgid, I wanted them to share batteries(lifetime warranty ad well). I also have a sawzall, and handheld wet/dry vac. Next is circular saw. I save $$ with my tools, they dont make me $$, but pricing/warranty/batteries was good enough for me. I also looked at Ryobi and was tempted.
I have the Ryobi 1/2 and 3/8 drive and used them to rebuild my front suspension and it takes wheels off with ease too. I went with the Ryobi mainly because my cordless tool line is all Ryobi because from garden tools to regular they all share the same battery platform. I wouldn't recommend them for professional use but are great for home use.
