What is a good inexpensive wide band O2 setup?

Innovate MTX-L is self contained and is pretty awesome and inexpensive.

The G-Tech Pro EGS is pretty awesome too, as it has many bases covered. Tach, shift light, Wideband, Accelerometer, data-logger. It uses the Innovate wideband technology, also. Kinda leans toward the ricer tuner look, but it is a compelling all in one choice.
