The DCS200 was easier to repair. Comes apart quickly, reseat the SCSI cables to the hard disk, started working again.
Getting any modern digital camera repaired is expensive. The photographer that took Nikki's Communion Portraits showed me a two week old Nikon D2x that was knocked over at a wedding, smashing the screen. The damage was not covered by the warranty. The repair estimate was over $1,000. Leica is not the only company that charges for repairs, it is expensive to work on these cameras. They are jam packed with electronics, more difficult to tear down, and more difficult to find the bad part or connection.
I've taken some computers apart to fix them, again easier with the older ones. Today's electronics are made to last about 5 years. If you are lucky. The stuff from the 90s was made to last longer, as hard as that is to believe. I still have 1GByte IDE drives working daily without problems. I keep multiple physical drives in my older computers, keep a copy of work on them.
