I have an old ATX890 that came with stock SID XC 2001 I think. My LBS said that it needs servicing done. But then, they also said it'd probably be easier to just replace it since servicing costs so much.
I also bought a pair of 2002 MARS Elite w/tcp lockout. I'm planning on spending some money ($40?) and overhaul them myself with new enduro seals.
Now my question is, should I replace the SID with the MARS? I have never ridden the MARS so I have no idea how they feel. They do cost less and are much easier to maintain with microlube..... And they are also probably as light as the SIDs... I dont ride much XC, just do mostly daily commuting (~40km) on very bad road conditions here in montreal.
Or maybe I should service the SIDs myself (though it would cost ~$60 just for the materials, still much less than the $150+ to send it out), but these require more attention for maintenance.

thanks all in advance~
hm... maybe i'm in the wrong section to be asking this sorry
