Does anyone have a suggestion for a reasonable rate I could rent out a Musser M31 Kelon marimba?

I used to rent out a 4.3 octave Yamaha Padouk marimba from my teacher at the time. I believe it was $75 a month. That is just a suggestions. There was also a contract involved as well as a security deposit of the same amount.

Are you saying that you have a marimba that you want to rent out? Because I am looking to rent one for my son who is 16 and a very serious percussion student--future percussion-major type.
