My Korg that I bought ages ago while in college is probably near the end of its life. The internal speakers are so weak that even when I crank the volume up all the way, I can hardly hear anything coming out.
I don't want to say exactly how old it is because that would reveal my age. lol. However, let me just say that it is wellllll beyond the warranty period. In addition, for what it may cost to fix this one, it may be better to put that money into a new keyboard.
I've thought about just breaking down and buying a real piano, like a really nice yamaha studio upright or something similar. However, I probably won't be buying a place until later this year or early next and I'd rather spend the bigger $$$ for a real piano when I can more properly match the instrument with the acoustics of the room.
Besides, I think I will always want to have a full size high end keyboard. The most important thing is the touch response and overall sound quality of the piano. I don't necessarily need a ton of built-in instruments.
