Marantz in the UK have now stopped the 9200 I believe and have bought out the 9500.
It really depends what you are after from the remote - if functionality is all you are after and dont need a load of memory and color is nothing major then get the 5400 - which still has 8mb memory but is greyscale as opposed to some stupid amount of memory in the 9500 which is colour

I have the 5400 and I like it, would have preferred the 9500 but couldnt justify the extra money just for a colour screen
