No idea where exactly it's being sold but I'm sure there are several places on the 'net.
I used it during a weekend among "foodie" friends who decided to check it out on a camping trip. We made several dishes with it and the general consensus was it was a pretty good fish and chicken cooker and the poultry cooked best when butterflied. Due to the use of liquid it didn't do well with dry roasting or high heat searing and grilling of red meats like burgers or steaks. However it made a really mean pot type roasted beef. Was fine for sausages and franks though. No char or grill marks on skewers or really anything. Nicely formed eggs but again lacking color and a bit rubbery.
These notes are about..7 years old and perhaps the grill has been improved since then.
I think it would make a good secondary cooking tool.
