Well im looking to replace my trusty microsoft keyboard with something quieter!. Im ideally looking for something that has a wrist rest as im constantly using a mouse mat under neath else!(the desk is sharp).

The keyboard must not be to loud(quieter than the old keyboards)
Cost ~£15
Some media keys(bonus, not needed)
Be full sized(no cramped squashed stuff)
Reliable
Good typing feedback
Comfortable

Any suggestions?
Been thinking about the OCZ alchemy one from ebuyer for £10 but im unsure as its a mix of membrane and mechanical iirc and i love the feel my MS keyboard gives so im undecided.
