My experience with Becker Autosound has been good. I just ordered a radio for the 280SL from them- getting one from them which was already restored was actually cheaper than the (unrestored) ones I found on eBay. The 113 radio, the Europa, is not the same as the one for the 108/109 car and other contemporaries. I suspect they are the best shop for Becker radios, because basically it is all they do now.
