Washer Drain Lint Trap Advice NEEDED:

[Nana Beans]

I just did a $170 dance with rotor-rooter because my washing machine was clogged with lint... WHAT choices do I have for a "drain pipe lint trap" (i don't have a laundry tray) Pro's? cons? Where to buy? Amount of space/room needed? ANY helpful advice greatly appreciated!

Thank you!
