There is a gentleman on EBAY selling these with a converted battery setup. The mercury batteries are very expensive, hard to find and a liability to dispose of properly. Do you plan to remarket these or distribute among friends? You may want to crunch some numbers To see what your final unit cost will be. Surplus can be very tricky. Sometimes incredible stuff slips through. A former Blue Angels F- 14 is on EBAY, additional assembly recquired. On the otherhand, theres a reason for surplus: obsolescence, design failure and gross wear. Again, for all posters: A brief mention of your association with, or commercial offering of a product is no problem. If your posts come with neon banners and high kicking emoticons for " Square Deal Donnie's survival gear and herbal supplements" it's another issue.
