all auction houses are joined so what you find in windy will be what you find everywhere else, the only way to get low lvl gear these days is to make it yourself, make a friend who has their crafts leveled to make it for you or farm nm's that drop gear. Really its pure luck finding low lvl gear at this point in the game as it is no longer worthwhile for ppl to craft it. There is some you can buy from npc's but after lvl 10 or so it becomes ridiculously expensive. Likely you will be in low lvl gear until lvl 50 when you can start getting your artifact gear (which frankly isn't that great either) and from their it will be hard to find anything until 75+.
