I want to buy a decent world radio. Do the amount of bands (i.e. '12 band receiver') have any real impact? - world band receiver

Basically I want to be able to listen to pirate radio stations in the crazy world when I travel this summer. To do this, I believe that a radio wave long decent? I want to know if cheaper on Ebay are good before you try them with me ... Ideally, I would like a wind-one, but I have not found a radio alarm clock LW. Therefore, any help would be hot too!
