I would like to think the .US version is worth about the same, but the .info 3 letters have been hotter for a while. Though .info's seem to run hot and cold, and fading a bit lately. 3 Letter domain are always safe if the letters are quality letters, and especially if it's a well known acronym like this one (or better yet; a word). Also, the drug connection can work strongly for OR against this name to end users. Over all, a very solid above average acronym, great 3 letter domain. A keeper.
