I agree with the highway statement. People do not realize that the spider gears in them wear over time even if your not engaging them. This means that if you only use them maybe once a year or so,.. or less, they are not likely going to be worth it so much, as they likely could be worn out after 6-8 years, and only actually needing them that many times.
