I'm starting a renovation project at home & wish to purchase a cordless drywall screw gun. I saw a video of a guy using this screw gun with a cartridge type screw magazine. Awesome tool! While installing a sheet of drywall it frees up 1 hand to hold the drywall. You're not fumbling for a screw in your pouch while attempting to hold the sheet in place with your knee, elbow or head! I saw them online at a store in Cinncinnati, Ohio. The company is called "Nail Gun Depot". They sell every imaginable air nailer, or screw gun known to man. The particular gun I am interested in is "Senco Duraspin" model DS 215. It's 18 volt, comes with a charger, 2 batteries & a bonus of a free rotozip type tool for cut outs at the electrical boxes, window frames & doors. It's $259.00. Lowes has the Dewalt corded gun (without the screw magazine) for $139.00 & the roto zip cutter is $129.00. Total $270.00 - & still fumbling to get a screw in place. Any & all comments are greatly appreciated. I'm a little nervous shopping on line. Does anybody know if I can get this tool in the Niagara, Hamilton area? I'll even drive to the GTA if necessary.
