I've bought the S-470 in 2017. Still usins it ervery weeks! Easy to clean, to use, it's a real good BBQ. 
My error, analyse de space. 
The top grill for the bread as example is really not deep. 
The grill surface is also a litte to short for me. 
This summer I had 20 persons for an hamburger and hot dog party... the space was a little bit missing on the principal grill.
