I just thought of something, have you any experience with this type of cameras?
If not and you're in a hurry, you could also get a nice Bronica SQ set for starters. Here is an example:
As I said before, I would go for the Rollei SL66. But if you want a Hasselblad, you might also consider the Bronica SQ-series. They are as good (if not better) and have excellent glass, also for portraits. And are much cheaper. I bought a Bronica SQ-B new in 2004 instead of a Hasselblad and never regretted it.
So you could get the Bronica kit within/for the next 6 months and take you're time to find a nice Rollei SL66 in due time as well.
Just a thought.
