Not as fancy, but there are relatively cheap options such as the ScanGauge that plug right into the OBDII to provide that information. That's what I got (200$ or less depending on the kit, new or used, etc).
There's also a Bluetooth OBDII adapter that allows you to get the data on your smartphone/tablet/laptop, so it's much more expansible as there are many apps on most platforms. (That is, assuming you have OBDII, I know it's not standardized as much in AUS as it is here...)
