Several users complained of this same problem with the mouse on one of our
NeXTs so I (unsoldered) and reversed the microswitches (yes, the machine was
beyond warranty :-).  My assumption was that is was more important to have a
solid left button and people could live with a sensitive right one.  Not a
great solution but it buys us another year.

Personally, I use a Xerox optical mouse (the best mice ever made) on my NeXT.
The wave form doesn't match the NeXT exactly (someday I'll play with some
capacitors) so it's a little shakey moving across the screen (i.e. I don't
recommend this for others) but after seven years of using Xerox mice, I've a
hard time breaking the habit (once a Xeroid, always a Xeroid ;-).  My current
mouse is based on the pre-reenforced two button Xerox 8000 optical mouse
design, so of course the left button completely breaks off every six months
and the mouse cover has to be replaced--but that's another story.
