Yeah I was thinking about Nico's one.
I have used pesteam.it's OF last year, it was good as well, I may look into it. Emerson's always great but current, V5 is 2 months old with maybe a few updates, IDK if it's compatible with DP4, I know V6 is coming out in June, so there's waiting involved and I am not good friends with mr. wait ;D.
Also I have used last year Alber's OF, but the latest version is weirdly only 600mb... Edit: Okay, I see Nico's is also about that size. Weird, from what I remember, Emerson's was like over 1 gb...
The italian team one is outdated. And now I think Emerson's V5 is outdated as well and not DP4 compatible.
