I'm very happy with my W2. There was an issue with an intermittent in the sensor cable but that was quickly resolved. It seems accurate enough to me on a subjective basis - I have no Bird to compare it to. As far as resolution goes the computer display resolution does rely on LED's and is a continuous bar with a switchable peak indication. This is only the 2nd version of the diplay software and I'm sure it will continue to improve. I have a friend that has the LP-100A and it's a really nice meter but I'm not sure I want to pay $120 more for it.
