I'm very happy with mine. I'm too lazy and can't justify buying another Arranger because of a few differences some consider better. Just came in from my studio to read this thread. I was working on "Then You Can Tell Me Goodbye" and having fun with the Clonewheel Hammond sounds in the BK9. When all you rich guys go jump on your new Yamaha's and Kentrons let me know if you have a BK9 you'd like to get rid of. I may in the market for a 2nd if the price is right.
Not to hijack the thread to a different subject but it does a great job of backing me up when I sing and really thats all people listen to, the vocals. For strictly instrumental work its just fine too.
