If it weighs 3.8 lbs with it RTF including ign i think it will be great.A crrc45 weighs 3.63 lbs[dry weight???]what ever that means.Dont know if the weight includes ign.Will have to see what your total cost would be.My home depot doesnt have a ryobi saw[at least on the website].I guess ill call and ask.The crrc 40cc kit weighs 2.87[again-dry weight].But,you made your own and i know parts are going to be easier to get.[priceless]
