Chainsaw Repair

Im hoping that somebody will be able to tip me off where i will be able to save a bit of money.
I want a pair of external circlip (snap ring) pliers to remove the circlip that holds the clutch drum in the bearing.
It is from a Stihl FS400 plus many other models.
Stihl charge an arm and leg for the official tool. The only suitable alternative i could find wont ship to me in the UK.
The tips need to be at least 70mm long and fit in the 25mm recess.
Below is a screen shot showing the tool and the Stihl part number
