precision camera, a forum sponsor, does mine and provides hi rez scans as well. awaiting my first batch from them any day now! thers no problem developing as far as i can see. the problem might be in the scanning as some places charge more because of the 'hybrid' nature of having negatives switch back and forth between normal and pano. precision camera does not charge extra for this, thats why i gave them a try.
btw, the xpan is far and away my favorite camera, film or digital. if you can get a good deal on a full set, go for it. the IQ rivals medium format, and its tremendously creative and fun to use.
