CharBroil has a MUCH larger version of this that is made for cooking turkey, it is propane powered, and it comes in at $99 at Big Lots and some places online (plus propane if you need), it can do up to 16 lb turkey, but also chicken, roast, and many other things.
If the small one doesn't cut it for you, may want to check it out!
CharBroil no oil turkey fryer.
