Hi,
the SD1+ is actually the top of the line model, though I think it's been out for quite a while now. I got mine last xmas.
It hasn't been replaced yet.

You could download the sd5 manual & do a comparison of the features. http://www.ketron.it/prodotti/index.asp?idTipo=2

You may find the sd5 has some functions the sd1+ doesn't & vice versa.

best wishes
