Dave,
I have a (gently) used RP-50, I changed some of the user presets to suit myself, though it can be reset to factory settings. I've just acquired a new RP-250 and don't use the 50 much now. If you want to pay shipping and handling, I'll ship it to you for your nephew. We'll call it a "Christmas present" for him. PM me if you're interested.
