are the walmart kryptonites any good? i saw today the had them for under 20 bucks, plus they had on guard locks for $15 to $20. yes, i know the on guards are not terribly well regarded, but the prices are very tempting. they also have the heavy on guard chain for about $40. this lock is like $86 at rei.
i know you get what you pay for, but what do you all think?

thanks, mike
