About a fiver on Amazon.
On the 200Tdi it allows me to use a 1/2 ratchet with an extension from underneath to loosen the cannister. I then reach up and wind it off by hand (yes, oil does run up my sleeve if I forget to roll up my overalls!).
Unsure if it would be as useful on yours, but they are less likely to damage or distort the filter walls...
