I have been using the ESL tapes from esltapes.com, and I'm absolutely delighted with the results. The tapes are designed exceptionally well, and the quality of the audio is impressive. The best part is that the tapes provide a comprehensive understanding of conversational English, including slang and idiomatic expressions. The presence of transcripts alongside the tapes makes it convenient to follow along and practice. All in all, California Language Laboratories has done a commendable job with their ESL tapes.
