MikeDouble check with the support person on the "as soon as they receive mine" part, since as I understand it, they will mail the replacement as soon as you give them a UPS tracking number for the one you sent back.
Of course if you are mailing yours, that may not be the way they do it, but you can use the delivery confirmation option with USPS for 40-cents that I think may now provide confirmation of shipment.
