I know I've posted about this before, but when I roadtrip, the A4 comes with. It's light, fairly easy to keep clean, fits on most hotel countertops. I use it on the patio during pleasant weather for al fresco cooking. I do have all the accessory pans, I paid full price when the A4 was first offered. @JoNorvelleWalker makes a good point about the takoyaki pan, it does a good job for meatballs and egg bites. I am more than satisfied with the device and accessories. I did order the deal for a second one as a backup or possibly a gift.
That being said, there are very similar appliances like this one (eG-friendly Amazon.com link) that exist. I don't think it's an unusual cooker appliance in Asia, but in North America, it's a bit of an anomaly.
