I bought one at Best Buy. For anybody who is interested, be sure you play with one before buying - I like it overall, but I have a really tough time adjusting the volume. It's a completely smooth plastic knob to change volume, with no indentations, and no way to grip it. I just ordered the remote from their website (my model didn't come with one) - I'll have to use that to change the volume...
Just FYI.
