On a related note, if you love(d) RadioShack, be sure to check out Akihabara ('Electric Town') in Tokyo if you ever get a chance. http://www.kirainet.com/english/radio-center/. I have never seen so many electronic components on sale in one place. It was even possible to find "vintage" ICs.
Reminds me a bit of the Yongsan electronics market in Seoul. I've never been in a building before with a hundred different stores selling nothing but PC power supply fans.
