Well, if your goal is "cool," I suggest you get a speed graphic. They are generally designed for use with a graflock back, which means you can easily attach a Polaroid back to them. You can also attach a roll-film back (I.e. Medium Format) back. It oven has basic movements, like a view camera. Be sure to learn about them first. There are many options. You want one with a rangefinder.
I'm not sure you need links. I think what you need is to type the camera names in Google, see what appeals to you and then do some research on that specific camera. There are resources on just about anything.
For example, speed graphic:

I can tell you that all the suggestions I have read have merit.
The 645 you posted was a decent camera. I think most medium format cameras which were used for professional photography are worth putting on the list of possibles.
My personal opinion is that if there is a camera you really want, find a good copy for a good price. There is nothing wrong with a Bronica, for example.
But if you really want a Hasselblad, get one. Don't like it? Sell it again. The Hassleblads will be most likely to retain their value because they have the name. After six months, you are likely to get what you paid for it if you get a decent deal and you are less likely to have trouble selling it than you will with other brands.
There is a reason they were so dominant. They worked well. Like any system, there were issues, but once understood, they were reliable. They were quite handy for an SLR which shot 6x6 negatives. They fit nicely in the hand. The weight was reasonable. The mechanics were nice and reassuring. And the babes really groove to the click and wind sound they make.
