Sorry Fran, I don't agree...technology has advanced considerably since the G-70, which was good in it's day, but sadly, is outperformed by a MOTL range BK-5.
Not just the sounds, but the styles do sound way better to my ears.
Just think, an MOTL S910 sounds better than an original TOTL Tyros.
It's no different with the Roland stuff.
If you are happy with your old G-70, I am glad for you...you can save your money.
However, the newer Roland stuff just sounds better all around...perhaps if John Smies was working with Roland gear, you might even be able to enhance your G-70 and bring it up to today's standards.
