The Panosaurus guy? I honestly don't know if he has a storefront or not. Good guy, though. I've lost and/or destroyed bits and pieces of my Panosaurus twice now, and both times he just sent me a free replacement part. Of course, they weren't anything big or expensive, but still... I thought it was pretty cool.
You really should give it a shot if you're interested,
Rat. Everybody has this idea that making panos must be either highly expensive or insanely complex. The fact that
even I can make them should serve as overwhelming proof that neither is true. I think the head itself cost me about $70, the software I stitch the images together with was free, and everything else you need (camera, tripod, remote shutter) was stuff I already had.
As far as the complexity... I'll admit the initial set-up was kind of a bitch, but it probably wouldn't be nearly as difficult for someone who could
do the math. I'm critically and chronically math-impaired, so I ended up just using trial-and-error with the adjustments and taking pictures until the perspective-thingies lined up about right. The nice part is that once you get it set up to work with your camera, you just tighten all the screws down and you never have to mess with it again.
Even the onsite procedure is pretty simple. The hardest part is probably answering the questions of all the people who show up wanting to know what you're doing.

Basically, it works like this:
1. I set up my tripod, and make sure it's level. (usually they have bubble levels on them)
2. I hang my camera case from a rope under the tripod to add some weight to it - helps keep it from moving around while I'm taking pictures.
3. I unfold the Panosaurus and attach the camera to it.
4. I attach the Panosaurus to the tripod and level it up. (it also has a bubble level on it)
5. I turn the camera on and attach the remote shutter cable.
6. I look at the LCD screen and fart with the Panosaurus' up/down adjustment until I get about as much sky and about as much scenery in the picture as I want.
7. I start from the right, about where I want the right side of the panoramic image to be, take one picture, turn the Panosaurus 10 degrees to the left (it has a little compass deal in the base), take another, and so on.
8. I usually take about 20 to 24 pictures. I try to get a little to the left and a little to the right of where I want the final image to be, because I always end up cropping off the edges.
9. I go home, load the images on the computer, feed them to Autostich, and it wallers them around for about 15 minutes and eventually spits out a panoramic image.
10. I load the final big-ass image in The GIMP, crop the edges, tweak the brightness and contrast and things, save it, and upload it to Wikipedia.
...and that's really about it. See? No voodoo.
