Trick Flow heads

Are you guys with the trickflow heads going with trickflow Retro-Fit Rollers? Any recommendations on a cam?

I was thinking about getting these heads later on, but I noticed they need roller rockers. I have a flat tappet Edelbrock #2177 Performer-Plus camshaft, so I would need to upgrade the cam, rollers, and rockers (additional ~$2.4k). It's starting to snowball quick. Maybe I should just go with the Edelbrock RPM heads? It seems like less money overall.
