George Kay is one important GEM dealer.

I know GEM WK2 but not WK1. if WK1 is the same as WK2 in styles and sounds, I would recommend the PSR line. WK2 is the most powerful oriental keyboard for its price. The only way to beat its oriental styles and sounds is to go to Solton X1 oriental but that is double the price!!

But when it comes to non-oriental styles and sounds, PSR line wins.

So the question becomes what about WK1?

Now in terms of ease of use, I liked PSR2000 more than WK2.

In terms of sequencing and other workstation features, I will take GEM anytime over Yamaha.
