The Dayton sub is great, and the shipping on it isn't that expensive. They have excellent customer service as well... I have the sub 120, 12" sub, and the amp recently decided to fry itself when I was sleeping. It was still under warranty, so they gave me a RA # and I sent it back. There was no hassle at all, I just told them what happened, and the told me to send it in. They sent my replacement back pretty quickly, and they are even sending me a check to reimburse me for what it cost me to ship the amp back to them. I should be getting the amp tomorrow, so hopefully it will be in good order. I also got the 10" version for a friends system, and it's been great, with no problems.
