I've been diving into the rental market and while I'm still just a little guy, managing my collection isn't so bad but I can definitely tell how if I had more cards a good bot would definitely be the way to go.
Thanks for a great comparison if / when I decide to use a bot in the future!
I would take a look at both. A rumour passed my ear that Rent Golem is now 10%, but I am not sure. It's still double that of SplinterRents, but you get all the UI goodness. They are both valuable tools we can use.
10% isn't so bad but I'm kind of a scrooge mcduck, try to keep every penny or in this case DEC hehe.
