I'm not sold on the whole I.R. cooking method. That fryer would be similiar in theory to the "
Flavor Wave".
As far as a oiler fryer, you can always make your own. All you need is a large heavy pot, a stable base, and output burner. You also need a high temp thermometer to measure oil temp. If you google "Good Eats Turkey Fry" you come up with a three part YT video, that has Alton Brown constructing one (and a turkey frying derrick).
If you just want to buy one off the shelf my recommendation would be propane, electric models have a heating element that has a hard time bring oil back up to temp. after putting in cold turkey. One with a high BTU burner will recover quicker, also a heavier gauge pot will hold/distribute heat easier. The thing with propane is many models require you to maintain the heat level yourself (most electic models have a built in thermometer).
There are plenty of articles on how to fry a turkey. You can always put the turkey in the pot, fill it with water till covered. Then take the turkey out and make a mark where water level is. As stated before make sure your bird is dry, have a lid handy, and don't do it indoors, that includes your garage. Really these things aren't that dangerous if your IQ is above 60. Hot oil burns if exposed to an open flame, just make sure that doesn't happen.
I've fried a number of them and never had a problem.
