This past Christmas I received a Presto Cool Daddy Deep Fryer from my wife. She got it on Amazon.
Since I didn't want to make my own shredded meat, and since I love the barbacoa at El Campeon in San Juan Capistrano, CA, I decided to buy the barbacoa and corn tortillas. I also bought 1.25 gallon jug of Kirkland Canola oil from Costco, even though I only used 8 cups.
All in all, the Presto Cool Daddy worked great. It heated up quickly, kept its heat during cooking, and was a pleasure to use. It stays clean due to the lid. The tacos came out great.
I posted two videos to YouTube, a long, verbose version (11 minutes) and a short version (3 minutes).

Embedded here is the long version. Enjoy!
