I just purchased a 4311 from them, ordered it last Thursday and it was delivered Friday. Unit was in perfect condition, looked to be a new unit with the latest firmware updates applied, all I had to do was register my unit and add the AirPlay feature. This was the second receiver I purchase from them, I bought an Onkyo unit a few years ago, again it was in perfect shape and during the time I used it I didn't have any issues, it is now in my step-sons house powering his home theatre. Great service and easy to work with. Didn't hesitate to go with the refurb, why spend an extra $200 for new when you can't tell the difference? Highly recommend using them if they have something you need and the item is competitively priced. Much better than a scratched warehouse deal from Amazon or from an unauthorized seller - what they sell they are authorized to sell. Nice to have the warranty and they offerer extended if you are inclinded to buy that sort of thing. Not all of what they sell is refurbs - some great deals on new equipment when in stock.
