I'm not sure what your videographer friend meant by requiring special docking stations. All consumer HD formats (HDV,AVCHD,DVCRPROHD) all use the same firewire interface as MiniDV cameras, and all fairly recent editions of editing software can handle HD video.
So I wouldn't rule out HD just yet, especially if you want to future proof your movies.
That being said content is king. If you have a good story, people will watch regardless of what it was shot on. David Lynch is shooting his next film on a MiniDV Sony PD150, and I'd much rather watch that, than this years next cop/buddy movie shot on 35mm film.
Either one of the cameras you mentioned in your post will do a great job.
Good Luck
