Which is better for smoothies?

Both handle smoothies with a 64 oz jar and a tamper. The Drink Machine's two speeds are enough for most smoothies, but the Vita-Prep's variable dial lets you slow the blades for chunkier textures or speed them up for a fully smooth result.

Is the Vita-Prep worth the extra money?

It costs about $89 more at current prices. You pay for the variable speed dial and the longer track record of ratings. If you only blend drinks, the Drink Machine covers that for less.

Which has the stronger motor?

The Drink Machine lists 1.7 kW, which works out to roughly 14 amps at 120 volts, against 11.5 amps for the Vita-Prep. On paper the Drink Machine has more power, though both are built for heavy use.

Which jar is more durable?

The Drink Machine uses a Tritan jar, which is more resistant to cracking and staining than the Vita-Prep's polycarbonate jar. Both are 64 oz and both include a tamper.

Do either have a pulse function?

No. Neither the Drink Machine Two Speed nor the Vita-Prep lists a pulse function. On the Vita-Prep you can approximate pulse by turning the dial up and down.

The Vita-Prep states a 1-year warranty; the Drink Machine listing does not state one. Both are commercial-style Vitamix machines, but the stated warranty favors the Vita-Prep.

Vitamix Drink Machine Two Speed Blender vs Vitamix Vita-Prep Blender

Both are 64 oz Vitamix blenders with a tamper and a wet blade, so the real choice is control versus simplicity. The Drink Machine Two Speed runs about $375 and gives you two fixed speeds, while the Vita-Prep runs about $464 at Chef's Deal and adds a variable speed dial. Buy the Drink Machine if you want a set-and-go blender for smoothies and frozen drinks; buy the Vita-Prep if you want to dial in texture for soups, sauces and nut butters.
