Most of the bellyaches posted about prices involve "Reverse Cheapness", or "RC". RC is an affliction that causes people to shop for price only after they buy the item. They buy an item from a store, and find they paid more than list price. Or, they check prices on the web after buying from a store and feel duped. Let the blubbering begin!
Visiting a local dive store to get started with gear does not work for a person suffering from RC. They must recognize they have this problem. Just like we plan our dives and dive the plan, the RC sufferer needs to plan purchases carefully and execute the plan.
This should be included, for the common good, in dive training.
I think that you have summed up the cheap bastard phenomenon quite concisely and with political correctness!
This has been fun...and I'm almost out of glue...dang!
