Look on eBay or local Craigslist and you will find an endless supply of Hasselblad V system parts & accessories. The 500 C/M will also accept digital backs of various vintage & specifications. My two 500C/Ms have only one jammed barn door in 30+ years of service and zero problem on the Zeiss CF lenses. How does that sound for reliability?
The drawback on the V system are squareness, not easy to handheld and relatively heavy for its' size. According to urban legend, shutter speed of 1/125 or higher is a must when hand held any CF lenses in order to avoid mirror/barn door vibration. I did get away with 1/60 or higher on a 50mm lens.
Ditch the "standard" 80mm lens if you mainly shot landscape & portrait, unless you need the speed of f/2.8 or compactness. This lens is sharp at at all aperture, so you can pretty much crop the image anyway you want for enlargement.
