I need a source for a small, digital, electronic counter.  It needs to
have an LCD screen, a button to advance the number on the screen by 1
(so it starts at "0" and then goes to "1", "2", etc.) and (VERY
IMPORTANT) a button to decrement the counter by 1 (so if it read "20",
pushing this button would take it down to "19".)  It needs to be
lightweight (less than 100 grams) and powered off a battery.  You know
the kind of analog counter that a ticket-taker will use to count the
number of people that have gone through his gate?  An electronic one
of these would be completely acceptable, AS LONG AS IT CAN BE
DECREMENTED WITH THE TOUCH OF A BUTTON.  Many of those counters only
have an "increment" and a "zero" button; this is unacceptable.

I will give a tip if you find one that can be incremented/decremented
in larger jumps (say, 5 or 10), and another tip if you find one that
has a little built-in stand so it can sit on a table.  I will tip $1
for each vendor beyond the first, to a maximum of three extra vendors.

You may finf what you are looking for on the following Web Site

Hi Ross,

Someone could probably build what I'm talking about using one of the
modules on that page, but as far as I can determine that page does not
list anything with the kind of user interface I'm looking for.

Thanks for your help.

this one does multiples, but don't know if does decrement.  I sent an
email to find out
