Well you are wrong, and you are giving bad advice. Dude asked for information about quality straps, and your answer in two different posts in the same thread was, "I'm the greatest because I chose not to use straps and straps are for pussies".
Well that is real helpful. I think anything goes is where corndogs go to jerk themselves off while pretending to be king ding ding! Meanwhile there are people who need quality advice about training. Real quality moderation going on here.
On topic: I get straps from academy sports and outdoors for 6$, and I love them. They get better over time and generally last for about 6 months or so depending on home much you use them.

While I agree with your sentiment KelJu, I believe that the original poster can eliminate his grip problems for free by switching to an alternating grip. I based my original post on the fact that about 300 pounds was an issue for him grip wise. Usually grip doesn't become a huge issue at that poundage for people using an alternating grip. Nonetheless, your point is well taken.
To the original poster, straps are fine to use. However, I advise using them only when you need to. I think it is a fine training tool, but you should avoid using them for sets you don't need to so as not to cripple your grip strength and limit forearm stimulation.
Try EliteFTS - Powerlifting and Strength Training Products and Knowledge for Lifters, Athletes, Coaches, and Trainers for straps. Virtually everything they sell there is high quality, though it's often a little pricey.
