As mentioned on the radio thread, IMO a crank radio is sort of silly for a BOB.  The crank radio is for spending 5 years in the jungle but in a BOB you want to minimize size and weight.  Also, shortwave isn't that important.  Anywhere near a population center, even AM-FM isn't important; AM-only or FM-only should be fine.  
Walgreens has small FM-only earphone radios at $2/5.00.  They are POS, but the reception is decent, they weigh just a couple ounces, and will run 30+ hours on a pair of AAA cells.  At a few hours of listening per day, one of those with a couple spare batteries will last for weeks, which should be plenty for a bugout situation.  I have a few of these.
Sony makes a similar but much nicer radio called the SRF-M37 which has AM, FM, TV and weather bands, runs on one AAA and also weighs just a couple ounces, but it costs about $30.  Some folks on CPF have them and like them.  I haven't tried one myself.
