Need a new slide, lookin for some good online stores or classifieds

So my buddy broke my bowl tonight and owes me a new one. Im lookin for a worked bowl. unfortunately i need an 18mm even though i prefer 14mm unless i get an adapter. but Aqualab didnt have too many i liked in my price range for oversized. so I was wonderin are there any other legit sites like aqualab to order from. or maybe another place that has a classified section like we used to have here.
thanks for your help.
