I purchased the learning strategies course for Spanish but I didn't finish it. I needed something to use in my car and the LSC course is designed to be listened to in a relaxed state. I did pick up the vocabulary very quickly on the tapes I did use.
I also Photoread a spanish dictionary and a beginning spanish text book. I'm new to Photoreading so I'm not sure what I got out of it.
I recently purchased the Pimsleur Spanish One. I think it's great. I've listened to each lesson twice a day, once on my way to work and again 6-8 hours later on my way home. I haven't had to repeat any lesson more than these two times and I feel that I am learning very rapidly. I just finished lesson 9 yesterday so I'm about 1/3 through the program.
I highly reccomend the pimsleur method. Although I don't have much experience with any other courses.
