Hong Kong Digital Vision Blog has pictures of the Pentax "Imagesensor Cleaning Kit" (sic), only available in Asia with any regularity). I've wanted to get my hands on one of these for ages, because they seem to be easier and cheaper than Sensor Swabs. You get way more reuse for the $39.95 US price. Importantly, there isn't a proprietary cleaning solution to wet the stamp tool.
In North America, selling these Pentax branded kits would be like condoning to the average consumer that poking around your camera's sensor is easy and safe for kids of all ages. Which is not true, it requires a really steady hand. That's probably why it's not something you can buy over the counter (aka. non-import). Overall, we westerners don't exactly have a good reputation as consumers who take care of their electronic belongings.
I feel we should be able to buy it here, and not be treated like kids with sticky fingers, but I'll bet the void of branded swabs has something to do with a cost evaluation of how much money Pentax, Nikon, and Canon would spend supporting these kits in the U.S., given all they've learned about impatient Americans gumming up their cameras through years of customer care phone conversations. I can just imagine what the average support call would be like:
Caller: "I followed the instructions with the sensor cleaner and now my camera won't work!"Still, I want one. Santa, I promise I won't poke my camera's eye out.
Tech: "Sir, did you really read the instructions and take all the listed precautions?"
Caller: "Well, no. But listen. I'm an adult who clean ears with a Q-Tip, and I haven't made myself deaf yet. I can drive a car. I can use sharp cutlery. I'm not an imbecile. What kind of a fool can't use a little plastic swab? Your product intentionally broke my camera, not me!"
Tech: "Sir, you're saying an inanimate plastic swab, designed to help you, defied all logical convention and directed malice against your camera and attacked the sensor? Yeah, uh, I've heard that one before."
Caller: "Exactly. So you admit the sensor swab is capable of evil! I'll see you in court!"
