Hi Miden,
are you still looking for a keyboard?
If you're considering a Roland, I've noticed an occasional VA7 pop up on local ebay. There's one going at the moment, also a G800 ( they're a bit long in the tooth by now). Even noticed a Ketron X1.

If you after something better quality I'll sell you my Ketron SD1+ haa haa.

Seriously though, at the moment I'm happy with my psr1500, I do like the Yammie styles. I bought it as an interim between deciding whether to get a T2 or the PSR3000 replacement. Figured I'd lose less in resale buying the 1500 rather than the PSR3k.

Before you dash out and buy a Roland, make sure you like the styles, I had a VA7 for a while, unfortunately the KN7 came out shortly after me purchasing the VA7 from a friend, the Va7 sat in the corner for months, virtually unused.

You may find the occasional PSR3k pop up on ebay, even though pro's may be reluctant to upgrade to the new s900 from the 3k , crazy hobbyists like myself tend to upgrade whether there's a huge difference in features or not, we just like to have the latest.

best wishes
Rikki
