Most desk jockeys wouldn't know an LED from a transformer these days, so if you want to get it right, know what you're shopping for.
here in Aus we have Jaycar and their fairly decent for an elec shop
i thought radio shack was meant to be a proper electronics shop? lol
4 number led display for 44 cents online where i would pay $7 for a single number 7 seg display from Jaycar. you get the idea.
