You're actually losing functions by choosing the 134. The Tesla is, IMO, ugly as sin and, just like Busardo mentions in his review, the screen is placed in the most stupid area possible. Every time you move your thumb to tap a button, it covers the screen.
Honestly, the SVD, in my opinion, is the next step. The Vamo, Tesla, and ZMax are so... yesterday.
True in terms of style, but they all have pretty much the same guts and function almost the same.
