I also went with a Sapphire 34. Two travel reducer spacers in the box, each one 10 mm. The Fox 34 SC will save you a bunch of weight if weight is more important to you than quality suspension. But I didn't want the harsh, crappy damping of the Fox. The Sapphire and Factory 34 SC aren't a fair comparison as the Sapphire works, has small bump feel, good compression and rebound damping - all things that can't be said about the Factory 34 SC.
Haven't ever used a SID other than on an Epic with the brain. Without the idiotic brain mechanism, the SID is probably a decent fork.
On top of that, the DVO customer support is top notch. They will help with setup advice, or service questions. Just give them a call or email, they respond very quickly.
