you dont have to use a gauge, with most ecu's you'll have the wideband giving the ecu software a readout, so you can read it on the laptop whilst tuning, no need for a gauge.

and if you dont want to pull anything off you can run the wires out the back of the bonnet and through the passenger window from the standard o2 spot, cant really do that from the tailpipe...

If ya wanna pay $200+/hour for tuning, sure it's easier to just leave it to the pros.

Sorry. I'm sort of confused. Wouldn't it be waaaaay easier to have a device to check air fuel ratio's without changing the factory setup which may affect the way it is tuned to start with. I always see tuners use simple ones you clip to the tail pipe and do an on the spot reading. Wouldn't a gte computer use the sensors for tuning. Why would I replace one just for a stand alone meter??

If you have an aftermarket engine computer installed, the factory o2 sensor will be worthless 99% of the time. If you wanna save some money, you can install an o2 sensor and providing you have a laptop, you can tune yourself to avoid a trip back to the tuner's place every time you change something small... <- that's the reason I did it!

Plus you can always get another o2 bung welded into your exhaust, and leave the stock one alone, and who said it had to be tacky? you don't even need a gauge, you can wire the o2 sensor into the ECU, and read it all from a laptop if you're afraid of having a tacky looking gauge.
