I reinforced the base with a plastic cutting board as the coupler for 137 weighs around 45 pounds. The occasional bug gets in but stayed dry inside - i need a little ventilation which the clip lid does for me.

In my case, the motor for the vario is an antenna rotator and I have it outside of the box with a shaft that goes through a grommet into the box to turn the coil.  I had enough room looking back to put that rotator in my box but just left it outside.

>> I think I paid $25 for my rubbermaid tub and the garden tool box was over $150 for the cheap one..
>> 
>> I think the wooden box Mike mentioned is also good, especially if you can paint and seal it to prevent if from retaining water.
