I sold my 15 year old Fein to my brother in law, and bought a corded Vecturo about a year after they came out (so I could get and use the accessories like the plunge base). I also bought ALL the adapters so I could use the myriad collection of blades I had accumulated.
Problem is now ANY time I want to use the saw I grab the blade I want for the application and then spend ten minutes fussing with WHICH adapter, WHICH bolt, and WHICH orientation of the adapter to use to mount the blade I want.
AND - about a year later the Fein died, brother in law took it to the local nail gun repair shop, they sent it to Fein - who LOST it, and sent him the newest most powerful model as a replacement.......
Last - Every time I need it now it seems that it's out somewhere about a hundred feet from electricity......... This IS a tool that deserves to be cordless.
