Richard,
Absolutely acccessible.  As a totally blind guy I am very comfortable 
with the transceiver.  There is free Kenwood software which is nice 
also but I've always preferred to program mine from the front 
panel.  And yesm, DTMF.
There is the new generation of Chinese, inexpensive handhelds which 
have some speech and are reputed to be pretty accessible but I've had 
almost no experience with them.  When all is said and done, the old, 
rugged, reliable Kenwood is a great way to go.
