I have a
Klipsch iFi in my bathroom. It is absolutely insane. It's discontinued, but if you could find one at ebay, it makes great sound.
It works with our iphones, but doesn't support charging. The dock is getting a bit touchy, too. It's probably served it's time, but we keep limping it along.
iHome makes lots of stuff, we have an under the counter, and some other stuff around. It's so-so, but convenient.
