Thanks you all for your opinions so far, let's hope they still have it available.

some more data:

- The keyboard will probably never move from the house, weight is not a problem

- I am not leaning towards any brand, the main buying driver is the bargain price. I would get a Korg or anything at that price.

- Not afraid to buy open box (as long as it works as advertised).

* Can all G-70's be upgraded/updated to the latest operating system version, latest downloadable goodies etc, or I should look for specific models?

* How do I check what OS or other goodies are installed? Is there a key combination available?

Any other data/hints opinions you can give?
