Do any of you own an expansion board for your keyboard? I've been considering making the purchase and have yet to decide. The company where I'm purchasing my guitar has some and they are discounted nicely compared to others. Are they very useful or just another fad?

My sister received one as a birthday gift this year and she really enjoys it. I think if that type thing is something you enjoy then you should go ahead and buy it.

I do think I will enjoy one if I can decide on which I'd like to have. That will be the difficult task. I just hope it works as nicely as I've read.
