I bought one on Friday (late afternoon) off of Ecost.com and didn't feel like paying extra for the shipping, so I just chose the $1.99 ground option. Well, to my surprise, it arrived today at my house. So much for paying extra to get it here faster. It was shipped via DHL out of Tennessee I think to Des Moines, IA.
Here is a link to the rebate...although, I don't see it on most retailer's sites anymore.
