We too suffered a high failure rate of Gemstar PSUs but not all due to physical damage. The more recent replacements do seem to be lasting a lot longer now though.
Whilst we don't use docking stations, I have seen one and they seem to be fairly robust. They have a pole mount fitting and also ports for patient bolus and printer at the rear. Whether the original lockbox can still be used to house the drugs or whether another system is used I don't know.
