.... Now going to go for a new compressor.

You're not having much luck with the a/c on this car are you 
it seems that way on first look .... but on closer inspection ...
The condenser was replaced Feb 2013 .. at that point it was 12 years old so had done pretty well considering... the "company" (?) [shysters] who did the work broke the radiator, never changed the filter/drier, and it would appear never added any lubricant to the refrigerant - unproveable but seems likely - which subsequently caused the compressor to fail.
The system was left empty for nearly a year before the replacement from MarkDTM was fitted, this had had the bearings replaced in the clutch unit, but had been on the shelf for some considerable while I believe. On filling the system the aircon guy commented that the output from the compressor was very good for a refurbed unit.
IMHO it would seem that the high output pressure, the age of the filter/drier (14 years ??) and the fact it was left empty for so long, all contributed to the filter/drier corrosion problem.
The body seal leakage is just one of those things from using an "old" unit, I'm grateful to MarkDTM for his efforts .. he had no way of knowing the seals had dried.
It's cost me no more than buying a new compressor straight up would have ..as the filter/drier leak would have occurred anyway... the only hassle will be
I will have to change the compressor this time .. instead of getting Daz to do it as part of the cambelt change !!
At the end of the day all the bits are "consumables" in one form or another !!
