Hey internet gurus can anyone suggest a decent L/top computer with reasonable grunt /ram/speed and a few usb ports etc to plug in card readers etc all so i can wifi use it?

I cannot even get satellite net at home atm and the best way it seems is to use a wifi unit in my truck,high on a hill ..even that I need to drive 7 k`s to get reception but at least it would be better than using this public library computer.

Price range..say to $1200 AUD or so.

And a reputable place in Oz that is safe to deal with,thanks.
