Hi FredOster
Check out
www.synthplanet.com , I take it that you are in France they are in Belgum I think. As far as the PSR1000 and the PSR740 I would go with the 740 because of the Organ sounds , but if you got the money they have a good price for either the Technics KN6500 or the Gem WK8SE, both of these KB are super compaired to Yamaha , but they also cost more. If you`ve been reading the threads about the PSR2000, it does have its faults but if your a hobbiest musician you may want to check that model out ,its not much more than the 1000 and has a bunch more features. Anyway best of luck and I hopeI have helped and wecome to the forum.
