I would advice you to walk into the Yamaha music Square and check their offerings for your price range.
I had tried Soundglitz and Furtado's for a few Roland and Korg synths but for the price I thought Yamaha was more to my liking. Their piano tones in particular are pretty good compared to Roland. And all the good Korg synths were much pricier.
