I think the first thing you need to do, is list the mentioned 'best sq gear' you have... and what you'd actually be willing to trade for the DD subs.
I realize you recently got scammed... but at best, your post sounds a bit shady.
Put it this way; I've already had 2 members PM me asking to look into this post, and a 3rd has reported this post to the Admins.
Trying to help you out here... be more descriptive in what you have, and what you're willing to trade.
