True, cheap glow plugs can be a problem. I've had my car nearly 2 years and it's still on the same plugs it came with though!
The main problem with WVO is obtaining it. Nearly everywhere is tied into a collection contract by the company that provides the oil. If you have a source, you're lucky these days.
Here is my WVO contraption. With about an hours hands on time I can make 150 litres of fuel from very average quality WVO.

The method is as follows:
Fill to 3/4 full, heat to 40 degrees. Filter hot to 1 micron to remove suspended carbon (suspended carbon starts the gelling process, a hot pre-filter greatly increases the yield). Add 50L misfuel (about 25%), add cetane booster. Mix and let stand for a week. Drain crud and water at bottom. Cold filter off to 1 micron.
I've been running this blend down to -6 this year and the car starts easily and idles normally almost immediately. I can't remember the last time I had to change the fuel filter.
If you want to run WVO it's definitely worth investing a bit of money and effort in a decent setup. I went from hand pumps and sock filters to this. The previous method was slow, very messy and almost impossible in the winter months.
