What's some Good investmens at the AH?Follow

I've recently gone from San D'oria to Windurst. I've made a couple trips back and forth and so far, I've been buying cotton capes in Sandy (300-500 gil each) and selling them in windurst (800-1,000 gil each). Once I sell the capes I buy Justice Badges for approx 900 gil each and sell them in sandy for 1,400 gil each. Its a profit, but a long walk and long wait for 8 items to sell... kinda floods the market. I've been trying to look for better deals (like something that costs 2 or 3k and sells somewhere else for 4 or 5k). I'd have to purchase less of these items and therefore would have to wait less time for same amount of profit. If anyone has anything, I'll be willing to trade any I come across in the future. I figure maybe if different people are trying different methods, it'd be better than us all trying the same one. That would just level the prices out probably and make us no money in the future.
