I haven't seen any SCUBA dealer contracts, but I would suspect it doesn't say any of that.
If it's anything like the Appliance & Electronics Dealer contracts, which I have seen, it just says that the manufacturer can terminate the contract with no reason needed. And they do.
It's not exciting and there's nothing you can call a lawyer about. All that happens is that the manufacturer says "we no longer will sell to you" and the sales rep stops taking your orders.
I know you're all in favor of anything that will drive down prices, (I like a bargain too), however, nothing exciting is likely to happen in the near future, especially in regard to internet sales.
In fact, I was reading recently in a study (I beleive) by the FTC that the consumer's ability to instantly compare prices from a large number of dealers on the internet has actually increased prices in many cases, or at the worst leveled them off, since not only can the consumer see what each dealer's price is, so can the other dealers (and manufacturers)
