I'm a gun guy. I'm a Glock guy. I'm a streamlined Glock-guy. Everything is the same caliber, everything is interchangable, magazines and such. Using that same reasoning, to me, cordless power tools are kinda-sorta the same thing. One brand, streamlined. One brand, many batteries to fuel said brand. Streamlined. Are you guys of the opinion of one brand to rule them all OR just the best overall manufacturer of said tool OR the best deal at the time of purchase? It's taken quite a while for me to pull the cordless-trigger...because I over-analyze the ZOMG DO I WANT 12V OR 18V AND DO I WANT TO TRY AND STICK TO THE SAME BRAND OR DOES ANY OF THIS MATTER??!?!!1! Up until this point, I've rocked very limited amount of corded tools, because, ya know, 200ft of extension cord is super convenient to weild. But all I know now, it that I'm ready to pull the cordless-trigger, SO I'm picking everyone's brains for opinions and the such. Thanks.
