Cheers guys, I went for the Pipe Organ too - very happy with it. So many options and they all sound great.
Incidentally, I got the Country Pop MIDI pack but also the Dream Pop one which I had been looking at for a while.
The reason for getting this is that I often use EZKeys MIDI as the basis for Pad/String tracks but usually manually thinned out.
The Dream Pop pack already has some MIDI aimed at strings and which sound pretty good without any manual edits so that should save some time.
