There are so many of them out there these days. Motley fool are very cheap at <$100 but when you get in they'll be hitting you up to upgrade so I've given up on them. I agree that Livewire is a decent one but less stock picking and more general macro commentary.
I'd recommend giving Switzer a look in - that's one I've had for a few years now and I find it to be one of the better ones particularly for their price. They've got a paid investment newsletter www.switzersuperreport.com.au also got a free one www.switzer.com.au.
