Found a GREAT deal here:

DT Swiss XM 180 Air Shock - No Remote Lockout 2009 | Chain Reaction Cycles

To replace the stock RP23.

It's 10mm too long, (big deal, offset hardware will sort that out), looks like it should fit, anyone have any experience with DT shocks? They make great stuff overall from what I hear. Off to research now....

edit: not much out there, the MTBR review has a much lower MSRP than CRC website, so not as much of a deal.
