I've narrowed the choice of my new radio to a Spectrum DX6 or DX6E. The straight 6 has 2-3 features I don't need for the xtra $50. My only question is are they built of the same quality....and it's JUST those 2-3 features that sets them apart....or is the straight 6 better built as well as the 2-3 things? I don't care about any other radios in this post. THX
