I was looking at purchasing a commercial blender and it came down to some hard choices between Vita-mix and Blendtec.  I wanted something powerful enough to make ice-cream or sorbet. Specifically I was looking between a Vita Prep 3 and some accessories and a Smother Q 15 amp with 96oz and 64 oz jars.  I know there is quite a price jump between the 2 but I figured in the accessories  if I opted for the Vita Prep 3 making the purchase a little closer ($199( Whisper Blend Sound Enclosure)+ $485(Vita Prep 3) +104.99( an extra Jar)  = $788.99 vs.  $879(Smoother Q 15). End the end I went for the Smoother Q 15 amp and here is why.  The Smoother Q has a more powerful motor reducing the chance of bogging down its motor.  I also really liked the fact that if I wanted to I could reprogram this machine picking between 30 potential settings.  Finally the Wildside Jar offered with this combo really sweetened the deal as it is advertised to help in making smooth consistent recipes, more so then the 64oz jars.  I am very happy with my purchase would suggest either of these machines given this scenario.
