Looking at purchasing a second hand 4x5 camera for use with Landscapes, Cityscapes and Architecture.

Any suggestions on brand/model and lenses?

Plus what accessories are a must and/or nice to have?

I'm in Australia so things are a bit more expensive from what i have found so far and it looks like it may be cheaper for me to look in the US and have it shipped over. So if you have prices on what i should expect to pay, use the US price and I'll look atthe conversions and shipping expenses.
