Ranald and David,

Well said. I am all for truth in advertising, but consumers are going to buy what has the best value for them at the time. A traditional tank may well last 100 years and be the better value over the long term, but it is certainly a steep price tag at the outset. I think that most consumers, especially those with other expenses to consider, will trade off 100 years of service for a much lower price, and potentially shorter life span. This has been said many times before, but I can buy 3 UK's for the price of a tank, and probably 5-6 AK's or SWK's.
