I just ordered my UCommand 515 from Worthington Distribution - the webpage says it's $99, but I called and got the remote for $79 + shipping and handling - about $85 total.
I guess they offer dealer discounts to anyone who calls. You can order online, but I don't know if you get the discount.
You can check it out at:

Happy Holidays
