I bought the KSB6060BM. It has a 3 hp motor, and does its job very well making hummus, lentil flatbread, and smoothies. However, a few design tweeks would make it more user-friendly: the jar wabbles; a pour lip would prevent contents from running down the side of the jar; the rubber lid needs more rubber extending beyond the jar so that it is easier to remove. I like the heavy duty electric cord and the adjustable holding strap. It is easy to use and clean.
