The question is this. How often do you need to use it and how are you going to use it?
If you are talking about the occasional home type use then I would suggest something in line with the Presto or Cajunfryer. For the money these will serve the purpose.
If you plan to use this fairly often and more heavily, such as for vending or catered events, then I suggest you go with something more in line with the aforementioned Avantco or even a Globe PF16E 16 lb Stainless Steel Electric Countertop Fryer LINK
. They are more expensive but are more in the commercial line and you will be glad you did when it comes to cleaning/repairing and heavier usage. You get what you pay for with this type of equipment. Generally the higher the price the more heavily built and more reliable the item is.
