If I had it to do over again, I would look for these things.
1. Immersion heating coil, preferably removable/replaceable.
2. Simple controls and design.
3. No filters or other do hickeys allegedly to control oil or spray, useless.
4. Removable oil reservoir for easier cleaning.
5. As much stainless in a smooth surface as possible
