Query: Great place to start

This the second pimsleur language set I have purchased. Both follow the same methodology and work great. I really like the way they approach the key concepts you need to know to be able to at least have some chance of getting around in a foreign country. I also have Rossetta Stone and found this to be a much better way to get started. Once you have mastered this, you might consider Rossetta, but this is a much better way to start.
