Thank you for your thoughtful response. I'll definitely have to check out my cards again and list them up for rent again. I have no idea how much they are worth right now, or what is going on with them. But it's just an income stream waiting to happen I guess. I don't have the time to play and trade them. And I'm not wanting to sell them.
As for LEO, I've heard good things about it. I'll have to check it out at some point as well.
