I did at least replaced 2 to 3(in 2years) of them in my Ser3 till a mate had his done in stainless, so I had mine done as well and still was good after 6 years.
This will be my 4th one in since I bought the 130 in 2007.
I had to wait this long as for some reason here in Melbourne no one does stainless re-sleaving, had to get mine done in QLD.
And yes I rang around and around and around, no doubt some obscure out of the way place in Vic can do it, but bugger me if I could find someone, and for the $55 plus postage I wasn't going to look forever.;)
