I have the original RM-TP503 touchscreen remote with stylus, 2 manuals(the remote has its own!), and original box.
The reviews on this receiver are very positive; just google it. In fact, a whole section of a website is devoted to its features and owners. See it here:

I'll post a picture of the blemish when I get it pulled from the HT rack as it cannot be seen except when looking at it from the side a close range.
Thanks for looking.
