Rick Oleson sells a series of bright screens that I have found to be excellent replacements. They are about 1/4 the price of a Maxwell and a huge improvement over most of the stock ROllei screens.

If you think you will make use of interchangeable lenses or macro capability, I would say get a Hasselblad. However, I would suggest hanging on to your Rollei MX-EVS. I own both Rolleiflexes and a Hasselblad outfit, and for some types of shooting, the Rollei is my preference. I would consider the Rollei to be an easier camera to travel with as well as a less intimidating camera for street shooting. But the Hasselblad has tremendous versatility, and repair services and accessories for it are readily available. You didn't say what type of photography you like to do, and that may well influence your choice. Some have suggested the Mamiya rangefinder system. By all accounts this is a superb system, but not everyone finds rangefinders to their liking. If you like the reflex approach to viewing, I would suggest trying out any rangefinder system before you commit to the change.
