Don't know if this would be useful for any of you, but if you have the ID of an item, you can pull it up on the market in this format and you won't get any of those stupid renamed items:
http://steamcommunity.com/market/search/?q=appid:570+prop_def_index:4007
prop_def_index is where you would put the ID. I'm now fine tuning a script to grab the prices of items off the market, then I can display a price and a link of my site. Just need to figure out how many requests a second I can do before steam starts denying me. I think things like Autographs and Prismatic gems could be a bit buggy, since it can only the first page at a time, but eh.
Good to know that there is a way to search by ID. I thought there had to be, it just wasn't exposed very well on the regular market page. And the limit has to be somewhat high, otherwise how would D2L know what to price various items at for betting purposes?
