You do not need a deep fryer....use a dutch oven and a fry thermometer. gaobest, I don't know how often you want to make fries but it is a lot of work and is messy and then you are dealing with all of that leftover oil. The best fries are fried twice...first at a lower temp and then a second fry to crisp up. Plus. you should use a mandolin to cut the potatoes. Unless there is a big demand for authentic fries in your house I would stick to frozen french fries done in the oven. Or you can just make thicker and not as crispy oven fries with fresh potatoes.
