Fender MIM Standard Strat
Fender Deluxe Reverb
Digitech Bad Monkey

I'm in Adelaide so i've found BMusic.com.au to be helpful, cheap and their return policy is good. I got a Zoom GFX something or rather a few years ago, and they let me return it just coz it sucked.

So they're pretty good.
Good range too.
