The Dirt Jam Pro was kind of a lower-end Marzocchi fork. I mean, I have one, and it's been pretty durable. Heavy though. And does have a harsh top out problem (or at least some of them did); I partly fixed that with heavier weight oil, but it's still not as smooth as other forks.
Also, that looks like a size Small (21.5"tt) Black Market? If you're medium height or taller I think that frame is too short.
