Point taken, well said. Different strokes for different folks :-)
In addition to being a chartered accountant, I am also TEFL qualified and taught English in Barcelona for a year as a career break. However I agree that "one size does not fit all," the advantage of PIMSLEUR is a) no books and b) your accent will be perfect.
Your voice. Your choice :-)
There are no free resources - you still have to pay for broadband, and speaking with a friend costs in terms of transport and the coffees you consume :-)
