A lot depends on how much you want to spend. Just be sure any shortwave radio you buy can pick up Single Side Band (aka SSB), Hams use SSB almost exclusively. I would also recommend a portable, in case the sh** hits the fan.
In portables, Sony 2010( the best), Radio Shack DX 398( same as Sangean 909), Sony 7600GR
I'm willing to stack my tube Zenith TransOceanic and it's WaveMagnet antenna against any of the new stuff. Course, it weights about 20 pounds with the 90 volt batteries installed, but hey, it's lasted 50 years or so already. :)
