Brymoore,
If you ever get over Tacoma way, there are a bunch of surplus stores off of the Madigan Hospital/Camp Murray exit off I-5 at Fort Lewis. Take that exit (122?), hang a right, then another right and there are three of four stores that sell them by the case or individually. $50-$70 a case depending on which store and how fresh.
PM me and I can get more info for you next time I'm out there to drill.
If you're ever in the TriCities in Washington, call me and I can hook you up.
Give me some warning and I'll try to provide you with the best choices based on Take-a-knee's extensive survey of hikers in Iraq and Afghanistan (infantry?).
