Your link didn't work for me... so I couldn't see who was selling.
I always see if the member has an iTrader rating. You can view previous comments from members to see how it was doing business with them. Short of that, you're on your own.
I always Paypal the seller first... letting them know the money has been sent. At that point they should send your item out as soon as they can. Usually within a day or two is nice.
There are members who have had bad experiences, so you have to use common sense.
Good luck.
