Actually was in a good mood. I say that because I have played them, and they just didn't cut it for me. They have a very colored sound, and didn't handle the low frequency material that well IMHO. And the highs were shrill and thin. I wasn't impressed to much by the Sumo's either but I think they are a better buy than the Behringers. I really would suggest you to try to find a store local too you that can get one for you to try, so you can judge for yourself. You might find that with your Casio that it works for you (And it certainly has an impressive feature set for the price). And yes you could do worse for $200, but I'd hate to see you spend $200 and not be happy (I remember being 16 (Barely), and I remember $200 bucks was a LOT of money to me then). Go check 'em out.
And remember your HR family will still love you no matter what you choose.
