Realviz has a version of Stitcher that is simplified too, called Stitcher EZ. I've started to use this version cause it's quick and does a good job on the panos for our Virtual Home tours. It's also quite a bit cheaper too.
Open Stitcher EZ, select pano or tiled, open your images, hit stitch, wait for it to work, export is the format you need. Done.
