What is the "key component" that is now unavailable for the 7100? Is it a part likely to fail in the 7100? Are we now unable to get our 7100s repaired if this part fails? What is the Outlaw plan for 7100 support in the next 5/10 years?

I don't know what the component is, but I'll hazard a couple guesses.

1) There aren't enough parts available to sustain production, but there's a stock on hand for maintenance.

2) If cases arise in the future where a warranteed 7100 can't be repaired for wharever reason, a 7125 could be provided as a replacement.
