Another option is Autometer. I brought these in from the US through Summit Racing. From memory about $1200 landed but with the current strong Aussie dollar possibly less now.
They are nice and big and clear to read. The 3 across the top are all mechanical Liquid filled quages. They are very accurate and the needles don't jump about. All the small guages are 2 5/8" which is a bit bigger than your normal guages. The Speedo and Tacho are 5".
Cheers
