Hi Jonathon,
I'm glad you're enjoying the Great Ideas Letter! Thanks for the kudos. :) It's really quite inexpensive when you think of how much it costs per issue... And we put a lot of work into each issue too (I hope it shows). :)
And I'm glad you like the forum too! I do think it is "different" from most other marketing/business forums - I think we are blessed with a "quality" crowd of folks who share some pretty darn good stuff. I know I'm a fan myself of some of the people who write here....
As for your radios - wow, sounds like you've stumbled on to a great opportunity! As for selling them one-by-one on eBay, if the radios are identical, I think the listings will be no problem. With eBay's free Turbo-Lister you can just write the auction once, then repeatedly list it when convenient... You can also use Dutch Auctions to sell many at a time.
Another possibility is you can even fully automate your auction listings if you use a service like Auctionworks. With their service, you can automate when listings will list - so you can have the same listings list at 8 pm every Tuesday, Thursday, and Sunday until the end of September (for example).
The only work-intensive area I see is the shipping part - however perhaps you could get an order-fulfilment company to help out with that.
If you want to sell the whole lot, or offer a Finder's Fee, a good place to check out could be Jim Straw's "WorldWide Business Exchange" (WWBE). (I don't get anything from mentioning it.) I've noticed in the past that there are several of these types of ads in WWBE. So it could be something worth checking out.
All the best with your radios! Looks like it has the potential to be a real winner! :)
