Can't believe i am doing this i am selling my Tyros 3 to go back to an organ (partly cause i now play organ in church)

I have been offered an AT80SL or AT500 to pay 2200 in p/x for mine which i think is good deal

I like all types of music including church and theatre , and wonder which is best the 80SL oe AT500 , i know the AT500 is the latest model , any views appreciated thanks
