It is true that an upgrade to a Mark Ve and the latest OEM HMI would pull you out of the obsolescence path, for a while, but at what comparative cost?  GE states they will support their Mark V components and provide service through at least 2014.  Also, there are a number of third party vendors and that provide Mark V spare parts and, by read of this forum, a number of excellent experts that know those systems that can help out.  

The weak link is often the  and HMI and they are far less money to replace. In addition to GE, there are other companies that make replacements specifically designed to interface with the Mark V, share the data over Ethernet, track more tags at higher scan rates due to managing Stagelink traffic more efficiently, etc. CSE Engineering is one of those companies that has a product and there are at least 1-2 others around the world.  You are always trying to stay ahead of obsolescence curve. You might consider pushing out a major controls upgrade as much as you can in this case.
