I've had my RDI Tadpole sitting in its original RDI codura carry case with all of its adapters unused for over 20 years. I'm never going to be using it again so wanted to see if someone else was looking for one before I consider putting it on fleabay. I recall a while back some firm was buying them and doing refurbs for some government contract. Its in such nice shape, but of course after all these years the battery wont hold a charge. The 18v power adapter seems to still work OK.
