Yep, I bought my 90cm dish and C-Band LNB from Freeviewshop.co.nz actually. I too considered the dish pointed directly at Intelsat 5 and an off-set LNB for Optus D1, but looking at the forums it suggested that D1 was more susceptable rain fade and gave a weaker signal for SBS (although this is not applicable now).
I took the view that as I already had a 70cm dish for Optus D1 and had a roof where I was easily able to hide the 90cm dish that I would just keep them seperate.
