I purchased the ET a week and a half ago after running an Se Pro for almost 2 years. I have to say already, the ET is much better (IMO) than my Se Pro. I know there are people on this forum that say that if you have an Se Pro, don't "waste" the money on the ET, but I disagree. The ET seems to be much more stable and has so many more functions/options that were missing on the Se Pro. The information that the ET gives is much more clear than on my Se Pro. To be honest, I like everything better about my ET than my Se Pro so far. Still hasn't helped me find more than I did with my Se Pro, but thats not the machines fault, everything around here is heavily hunted out. I will still keep my Se Pro as my backup machine as I really do like it, but the ET has def already proven that it will be my primary every single time I go out. Hope this helps. HH -Marc
