on iss you can prolly find some ds ones but i hate dealing with some of the people through emails. Rif.la is basically a trade in/trade out place, so if you wait a while you could get some vnds ones maybe ever ds.
here is a ds one off of rif for 275, but might not be your size, wait a little until they get some in.
Also if you are in for the wait, Holy Grail is legit. They just got robbed during the lakers riots, but they have good prices and are re-stocking fast. they dont have dinos right now though. Flight club is a last resort if you want to pay 50 dollars more then needed for the shoe, and the shipping is like 20 dollars.
N-sb.org is also an option, but i also hate dealing with people on a forum instead of a store.
just keep checking these links:
