I don't particularly like studs and would never pay to have them on my tires. There is some thought that studs are only good in very specific conditions and actually increase stopping distance on bare, paved road. I bought my current set of winters used and they already had studs. I got them because a set of Nokias with less than a thousand miles on them for $500 was too good a deal to pass up.
