EGT Install - Where to, and suggestions on a kit? Good temp to read?

I'd like to get an EGT guage set up so I can keep an eye on my temps (this is on a 1.6 n/a but will be a 1.9T before it's all over). My questions are: Where is the best place to mount the bung for the probe? The manifold is cast and I have never been a fan of welding on cast metal. And does anyone have suggestions on a kit? I have found a Prometer setup for ~$100 (includes gauge, probe and bung) but am unsure if 'brand name quality' plays a roll here (as this seems quite cheap comparatively).
Also, once installed, what kind of temps should I expect for daily driving? What kind of temps should tell me theres an issue? Any help appreciated.

IF your going to do it:
Mcnally makes a very well made kit
Boost / EGT Temp
Complete 249.00
McNallyelectronics.com
I did all three in my center, I wanted something that was back lit with a good quality
Drill and tap the manifold , I ve seen some were you drill and clamp the probe in place

can the EGT probe not go in the downpipe just after the turbo? that was my plan. otherwise i have to remove turbo and manifold by the looks of things to tap the thread a hole for probe.

Placing the gauge pre-turbo right in the middle of all exhaust gasses is the best way to get the most accurate reading. Placing it post-turbo will affect the reading by I think.. ~200F? (i think that's correct anyways)

Yeah it sucks, but because the turbo removes a variable amount of heat, based on how much it's working (ie converting heat into work), the readings downstream are also variable and render the gauge pretty much useless as a danger indicator... by the time the readings peak the damage has likely already been done.

The probe part # is 10-01478. Here's a link:
http://www.aircraftspruce.com/catalog/inpages/micro8egt.php
Here's a thread with the Westach gauges:
http://www.vwdiesel.net/forum/index.php?topic=4785.15
The round face gauge that fits a standard pod is the 2C2-1 gauge (not to be confused with the 2C2) and must be special ordered from Aircraft Spruce or directly from www.Westach.com.
Right from andrew in my message box...
The only quarrel I have is the fact that the probe is a clamp on style (so... how do you seal it to the manifold so you dont create an exhaust leak?). Other then that the kit seems pretty straight forward. Any insight appreciated, if I could find a probe that threads in I would think it'd seal better, no?
Having a closer look, it seems it mounts to the clamp itself? Again insight appreciated..

Has anybody found a gauge that doesn't look out of place in an old Rabbit? I'm looking for a pyrometer that looks vintage: no LEDs, glowy needles, etc.
I didn't do a search, and I'm not trying to derail this thread. I just thought I would throw my question out there while everybody was making recommendations.
