The model e is very similar to the ridgid 400 and general minI rooter. Its not a great machine for hard stoppages.
I would stick with the eel innercore cable unless you want to swap out to a ridgid cable and cutters.
If you really want an all around machine and can swing approx $1700. Then get the ridgid k-60sp. Comes with 75' of 7/8" sectional cable and cutters and then purchase some 5/8" sectional cable and cutters. Between these 2 cables and machines, you'll clean everything up to 4" with roots and with innercore cable 6". Its my #1 go to machine for the last 7 or so years. All my drum machines are now collecting dust. Probably have enough drum machines and cables sitting in the shop to buy the biggest harley you've got.
Look up some of the k-60 threads for photos and stories from myself and all the other users.
