Can anyone suggest a good 2 jaw puller, the kind that come with the extra piece so you can bolt the two jaws together around what you are trying to remove. A co-worker bought the snap-on set for $500 and it works great, but thats a bit pricey or me at the moment. I see OTC makes a very similar set but not sure about the quality. I need something that can pull hard and not break, will be using it on gears, couplers, and pulleys. I have used the proto set in the past and it was built very robust, but it kept slipping every time I tried using it. I want to know what is working for you guys?
