Michael,
I sold my 940 a number of years ago, primarily because I had 
purchased an 850, but even back then parts were becoming 
problematic.  The 940 was my first brand new transceiver, and I've 
not had a brand new one since.  Logged an awful lot of contacts with 
the transceiver but look around, there are a lot of newer units which 
work well, and perhaps better than the old Kenwood.  I'm afraid that 
the 850 may become difficult to repair soon; I also have an Icom 
746PRO which I am very fond of.  I had a TS2000 but didn't use it 
enough to remember all its functionality, but it too is an accessible 
transceiver.  However, I personally prefer the receiver in the 
PRO.  And although not as accessible the Icom is a great transceiver.
Good luck with whatever you choose to do.
