Loved it, and to the person asking for an item to merchant....you need to find one yourself. It all starts with you finding one item yourself, and you get pretty good at merchanting that item then you just go from there. Look around, don't be afraid to lose a couple of mills trying to find an item. Because once you've found that item, I'm confident that you will make much more than what you lost because you would be competent at trading this item.
That's all I have to say to anyone else who would ask what item to merchant.
