Depends on what you mean by "fairly inexpensive, but Parallax sells their own:

Description Part # Weight Price Qty.
MEMKey #27963 0.06 lbs. $39.00 1

Price breaks in quantity are offered at 5+ and up.

Due to recent conditions I will leave for other their own
self-advertisement <sigh>.

Other references may be found in the StampFAQ. Sorry I don't have the URL
handy.

I think Bruce is referring to http://www.elabinc.com
Here is the offering:
The EDE1144 Keypad Encoder IC is designed to interface a matrix-type 4 row x
4 column (16 key or less) keypad to a microcontroller or other host
processor. A one-wire serial or four-wire parallel interface returns the
keypress data and can be used in conjunction with a 'data valid' signal for
polled or interrupt-driven applications. The EDE1144 provides enhanced
keypad features such as contact debouncing and key auto-repeat in an
easy-to-use package that will lower software overhead in the host
microcontroller and reduce the I/O pin requirements from eight to one,
frequently resulting in the use of a less costly host microcontroller in
your design.

Price US$7.00 in singles.

I have no connection with E-labs other than having purchased some of their
products and been satisfied with what I received.
