Is it possible to implement a top rated block section for my store?

[cstuff]

Hi there,

 

I have recently set up a store and want to customize the template i am using to include a top rated section in the sidebar which will list the top 20 products based on users ratings.

 

I have been looking at different rating modules but i can't seem to find any that will allow me to feature the top rated as a block on the homepage. Does anyone know of a module that will work or will it be a piece of custom coding in order to do this?

 

Any help/assistance would be greatly appreciated.
