16-bit address and data buses? Hardware multiplier, divider, and barrel shifter? I wouldn't exactly call it simple. The cost to build one out of discrete logic probably approaches the quadruple digits.

Magic-1 (http://www.homebrewcpu.com/) is a 16-bit, microcoded homebrew CPU that took about 4 years to build, and it doesn't have any of the above features.
