If you want to visit one site to find your components and com pair prices here is a great site.
Find Chips has a listing of a few major electronic components distributors, most will sell without a high order minimum dollar amount. Be careful with handling charges, some are very high.

Crystal radios are fun to play with no matter how old you are. The kit listed above is the Elenco MX-901 Crystal Radio. Four local stations came in loud and clear into my earphone.
WABC, 770AM, Talk
WINS, 1010AM, News
WEPN, 1050AM, ESPN Sports
WBBR, 1130AM, Bloomberg
The hook up was very simple, antenna wire hung over curtain rod, ground wire to a plate on radiator. The key is a good solid ground, make sure your connection is not made against some metal that is painted.
I am going to keep it connected for another hour and maybe get lucky with a station or two out of the local area.
