Hey, that sucks man.
I got my Infinicy 1230 W 12" subs from ebay (sellerID: oceans_no1 or eldirect [their the same person]) and I only paid $50 USD for both. I don't know how much shipping would be for you, but it's worth a try. I haven't blown these as of yet, and they are incredible with my deck (Pioneer DEH-P9600MP)!
Hope it helps!
