Hey there everyone! I'm about to spring for my first 2x72 and I still cant decide on which one....so I'm turning to you folks for some insight. I'm stuck between the Ameribrade 2hp variable speed option, the KMG 2hp 3 speed option, and the Pheer 454 2hp variable speed. All are priced about the same, but since I've never used any of these machines I'm asking for advice and some insight on which one I should spring for. Thanks!
