If you are happy to take the time and effort to take multiple photos of a scene, and I realise that this may be inconvenient at best and life threatening at worst, then you can use software to make extremely acceptable panoramas from multiple images. The end result can be very good even if images are not "square" to each other or evenly spaced. This has the advantage of allowing any camera that suits you best to be used.
One such program is the free and excellent "Autostitch" which requires almost zero user ability or input to operate.

Note that their demo photos includes an alpine landscape made up of a horrendous jumble of pictures. Using perhaps 6 or so more usual images the results are often a seamless image where the orginal boundaries are vanishingly hard to spot without extremely careful examination (if then).
One commercial product based on autostitch is Panorama plus at 12 GBP which adds extra functionality such as export to Facebook or Flickr, PDF output etc.
Apparently Kolor also use it in their software.
