I wonder if the anonymous poster who started this thread is still having trouble deciding between DH or TPG.
I am also from Australia, and for most of last year I went through the agonising process of comparing deals, reading reviews and etc to find the 'perfect' Australian web host. But the outrageously high fees charged by Australian hosts forced me to look for overseas alternatives.
I signed up with DH last month. Before that I had spent some time lurking about in this forum to get a feel of things. But it was all the 'happily hosted by Dreamhost' buttons I saw on so many well maintained sites that convinced me DH was worth giving a try.
Dreamhost seems to have lived up to their reputation so far: friendly, reliable and definitely affordable. Some say the lack of phone support is bad, but it is not a problem for me: for USD9.95/mo, I do not expect DH to set up an international free-call hotline for old me. I have found DH's email support good enough, and this friendly support forum is a nice bonus.
