SLM ... I play a technics kn6000 and I've created a backing file for "Unchained Melody" and I use a '50's style guitar strum on just the second beat of each measure (I think... I'm not at home so I can't check) ... I use Starkeeper's method of left to right, mostly 5 fingered chords ... sounds good to me ...
I've used a 'jazz guitar' strum on the left hand in an old tune called "Perdido" ... It sounds something similar to the 4 beat strum the guitar player in our band had when we played the tune (it fits in well in a 40's medley), but I guess if you listen closely, you could tell it's not a real guitar ... But then, it's NOT ...
