wow, didn't realise it was so (apparently) simple! mine has been making a few unsavoury noises lately but they sound like sucking, rather than squeaking.
TF Tuned have removed the Deluxe from their RockShox service sheet, I don't know if you could sweet talk them into it?
I did find another comapny that say they will, but I haven't enquired to confirm. It's on my PC at home, i'll post up the details later if you like
There were also a few upgrade options, such as a Risse Genesis iirc, and someone was doing a Fox/BETD rocker upgrade on ebay for a while. I went looking for it the oher day but couldn't find it..hideously expensive.
