Baz, I have recently purchased a iX 4000 Canon printer, to do just what you have said, and it is fantastic.
It will do borderless up to A3, and is reasonably economic to run, the colours are spot on, and it only needs 3 individual colour cartridges, and 1 black.
They cost about 25.00 each, but last a good lenght of time, if one is not wasteful of coarse.
I usually do a very small test print, say about 6x4 before i let it rip at A3, so that I know all is well with the colour and stuff.
The Canon iX 4000, is not cheap and cost me $600.00, but it is well worth it.
You can order one of these from any Camera House outlet, of direct from the Canon site.
Hope this helps a bit.
