Hi Bernie,
There is one on Ebay.
I have a Coiltek probe I will sell but don't have the little switchbox available. I suspect Steve Herschbach has them available, since that is where I got my box.
Take a look at the probe and switch setup to see what works well.
I was going to use the Coiltek Probe but I found I could use Eric's probes also, so I modified the box a little and use Eric's probes that used to come with the GS 5. I got a probe when I bought a used GS 5 but didn't try it because it normally has a resistor to reduce power to the probe. I ended up adding the resistor and using Eric's probe after all.
Now, one thing that can happen when you use the Coiltek probe is you may get a strange vibrating sound coming from the probe. That has happened on occasion. It won't hurt anything, but it does cause concern for some people since they are not sure what is happening. Again, you might ask Steve Herschbach about this, since he is familiar and found this "singing" noise appears to happen on certain TDI's.
