The UltraGauge and Scan Gauge II are both quite popular on here and just plug into your OBDII port. They are easy to hook up and use. I use an UG and am pretty happy with it (good features and inexpensive).
Both have one problem... they can't accurately report fuel economy on a Lean Burn engine. To do that, you need to tap into the fuel injector circuits and an MPGuino can do that.
Even with the UG or SGII, you can tell when it enters Lean Burn mode, you just can't rely on the MPG data while it's in Lean Burn.
