ipod dock / speakers

[CraigW]

hi all.
looking for an ipod dock to use on a boat. its not likely to get drenched although if there is a decent one with some element of waterproofnessness then it might be good (but thats not essential)

It might get nicked so price is a factor.

Cant be too large but i cant abide crappy sound..

open to suggesions (have bose ipod dock - not as expensive as that ideally)
