Drain Auger Recommendations

[gdr_11]

Has anyone got suggestions for a 1/2" x 50' drain auger to use on a 3" line? I have an ongoing issue with the short line from one bathroom to the main septic. I see the manual ones for $50 or less but don’t know if they are a waste of money or not. The electric ones are a lot more expensive and I am not sure if the cost is worth it if a manual one can clear common bathroom clogs

Rent an electric one?

Rentals are ok but the closest rental place is more than 20 miles away and I dont fancy putting a filthy drain machine in the back of my suv.
