I have a DSLR and a Hasselblad 500 c/m. I wouldn't want to give up either one.
Used Hasselblad prices are lower than ever, but as has been mentioned there are lots of other medium format options that are even cheaper. I love those Zeiss lenses on the Hassy, but the fact is most of my medium format cameras do a great job, including the cheaper, and less popular brands. I think you should be able to find a decent condition, used Hassy with WL finder, a film back, and the standard lens for $600 or less. But it's possible to start out in medium format for less than $200. Then you could save your money for a DSLR and/or 120 film and processing.
Do you have a good local lab that does 120 film? The kids in the photo labs these days, they're all up on the digital, but don't have much experience handling 120 and 220. I do all of my own BW, but I began to have trouble getting good service with color 120. I was getting a lot more scratches and fogged film from mishandling at the lab. It's the main reason I bought a DSLR when I did.
When I bought a DSLR it ended up being about four times more expensive than I originally thought. Besides lenses and neccessary accessories (extra batteries, cf cards, cable release, etc...), I found that I quickly needed a computer upgrade, and a lot more hard drive space.
I think of cameras like cars. The Hasselblad is vintage Detroit steel (Swedish steel?), and the DSLR is a modern, efficient Japanese sedan. The speedometer on the vintage auto has bigger numbers, and it's sexy and fun to drive, but either vehicle can get me to the grocery store, work, home, etc... The modern vehicle does it cheaper, quieter, more efficiently. Which one gets me where I'm going today just depends on my mood.
