Someone should have come up with this a while back. I end up buying and trying then if I don't like it I sell it. That's why I buys used and cheap in case I have to flip.

I remember seeing either this or another site doing the same thing a ways back, but back then the pricing was kind of silly.

If those rental fees include shipping, this is much more reasonable, especially for more expensive pedals.
