Sometimes you just need a big red LED display, prewired with driver transistors, current limiting resistors & ready for multiplexing:
4 digit, 12 I/O pins, $4.34 shipped http://www.ebay.com/itm/400427457742
8 digit, 16 I/O pins, $6.00 shipped http://www.ebay.com/itm/261053427167
I should point out (before xyz does) that there are cheaper LED displays such as http://www.ebay.com/itm/130888044808 but those require additional effort & hardware.
