Just for the records....
I own a G70 and a Tyros 2 and I love both of them as each one has advantages in some departments over the other (I like the PA2X and SD1 sound too but wife will never allow me to have more keyboards at home than I already have).
But...
If I had to choose only one to keep....G70 would be the one.
Keep playing and enjoy your life as it is sooooooooo short for the amount of music available to listening and playing....
