I also have that same fryer. Walmart had it clearanced for 39.99 a couple years ago. I like it, because there is absolutely no chance of boiling over. But be careful, I mean very careful when washing the element. I have had mine replaced 3 times.
I use peanut oil. It is more pricey, but you can use it more times because it doesn't burn like veggie oil does. Whenever I start a new jug, I always fry a turkey
first. Something about a turkey that makes everything else you cook just taste better.
If you have a problem finding filters, I used to go to a Taco Bell, sweet talk the manager and she'd give me a couple for free. Then I found them at Bass Pro Shop. I tried the battery powered oil sucker thing, it sucks, and not in a good way. I took it back for a refund. I let my oil cool down to about 150Âº, then pour it into a big funnel lined with the filter.
I use the injector that LEM sells. It's kind of expensive, but it will last the lifetime of me and at least 3 generations after me.
