Help. Ipod Nano dock extension at reasonable price?

I just purchased a iHome Kitchen sound system. It sounds great, price is right, and it has some nice features. Problem is, I cant connect my Nano unless I take it out of the plastic case I have for it. It big PITA. Anyone know if anyone sells a dock extender at a reasonable price? I found these links, put the price is outrageous.
