The current "Best rated rigs" is kinda unfair towards other miners as people vote more then once on the same rig and others get no votes at all as not all people leave feedback.
In the current situation people with 99 good rentals without feedback have no chance against people with 9 positive and 1 less positive feedback due a lack of score.

Best way is to remove the entire "Best rated rigs" section.

I also would like to see a few changes to the search filters..

Small < 1Mh/s
Medium < 3Mh/s
Big < 6Mh/s
Farms > 6Mh/s
