I have not used the above device, but I have used this other extractor (below) over several years for oils and a variety of other 'sucky' tasks, including emptying my MB fuel tank several times for filters changes and pump repairs. This unit is affective and durable, and holds a generous 6.5 liters. A big advantage over the 'gas can' design is that this one can easily be cleaned so that it can be used for other purposes.
I bought mine at Harborfreight for $40, but I cannot find it on their website anymore. They do list a pneumatic version for $60. This unit seems to show up at a lot of vendors under different labels. Griots Garage has the manual version for $65:
