I just connected (as in 30 min ago, yay internets) to TPG naked dsl. I went with them based on price/MB on a naked plan.
I wanted to stick with Optus cable, which I had been with for 8 years, because I was happy with the pricing and speed, but it's not available in my area.
Given my proximity to the exchange I think cable would be a faster option, but alas not to be.
So far my experience with TPG support suggest at least part is based in canada.
