I have the Sony D-FJ75TR, looks exactly like the DEJ711, but I have a tuner remote and mine is a darker silver. I paid full price for mine at the Sony store. Don't ask! Ever since I found Headwize/Head-fi almost a year ago, and found out anti-skip may alter the sound and/or battery life I have turned off the G-protection. It has not skipped, period. I ride my bike to work with the CDP in my backpack and my Sony still has not skipped.
The optical out works fine. I had a Sony MZR900 (japan md model) a few months ago, burned two Floyd albums on one 80 minute disc using both Sonys. Not a problem with synchro-record. Like a dork, I returned it and it was the cool blue. Anyway, I bought the MZR900DPC (US version) in pimp red. I'm looking forward to being reunited with minidisc once again.
I bought the Sony before I knew about Headwize, I may have gone for the Radio Shack 3904 or one of the Panas, but I love my D-FJ75TR. I recommend you pick up the DEJ711.
