All great reading. Would like to see how it could possibly cost "millions", to bring such products to the market; love to see some sort of break down; we're not talking production like that of a small car 15-25 grand for instance, or mass production like other recreational products. I have a prototype, design registered, camper trailer 1/10 scale I built a number of years ago that I have shown a few manufacturers, small and large, to gauge their reaction. Each one has commented on the marketability of the product in a positive way but each one has also said that it would take some ridiculous amount of money to bring to the market, which is just absolute crap. Where some of these figures come from is anybody's guess. Designing products cleverly so that they can be produced in numbers seems to be so overlooked in Oz., I have seen so many commercial products made in factories in such archaic ways that Henry Ford would of shook his head. The workers/technicians know it, but unfortunately the powers that be don't, they keep throwing money in to try to solve the issues, but fail to listen to those who really do know what they're talking about, and hence, loads of money wasted. I love the saying, "fail to plan and you're planning to fail". Doing so can save the investor so much money. Also, when it comes to successfully marketing a new product these days one doesn't need to hand hundreds of thousands of dollars over to some wiz bang marketing guru, to get good results; these days the internet has made it a truck load easier to bring a product to the market without it costing an arm and a leg. Sure there will be investment needed to bring any product to the market, but pulling figures out of thin air without being able to fully substantiate is sooo out of date. Cheers all
