I think you have to be less skeptical when you're reading books and just take them on face value and get what you want from them. The positive cashflow methods detailed in Steve McKnight's "0-130 properties …" are just one of several methods of investing in property, as are John Reed's (who I haven't read).
If you read Steve's book, you will find that when he originally started out in investing, the strategies of negative gearing and pure 'buy and hold' were commonplace (as they've always been), but when he thought about it, they didn't stack up for him. I don't think it was so much that he thought they were bad strategies, more that he was looking for a positive cashflow to replace his employment income and therefore allow him to stop working. This is where you need to work out what your goals are and then investigate strategies that might get you there.
The benefits of negative gearing are the simplicity of the strategy: you pretty much just find a place that you think will appreciate in value, have a tenant pay some of your loan repayments and then just wait. The risks are as you know, a falling or flat property market and interest rate rises.
If your goal is similar to Steve's, then negative gearing won't work for you because you will need another source of income (most commonly employment) to plug the funding gap between rent and loan repayments.
Positive cashflow properties are out there, but they are not very common, or should I say easily found and they take a lot more finding and structuring than simply logging on to domain or realestate.com.au and expecting to pick up one. As Steve said, positive cashflow properties are made, not bought and this is why he used wraps and lease options extensively.
As far as whether or not to buy John Reed's books, even though he's overseas, you may still learn something.
