1/16" diameter option
Thermocouple: TJ36-CAXL-116G-6-SB-SMPW-M, $38
Swagelok fitting: SS-100-1-2BT, ~$12
1/8" diameter option
Thermocouple: TJ36-CAXL-18G-6-SB-SMPW-M, $39
Swagelok fitting: SS-200-1-2BT, ~$12
The Swagelok fitting is a one time only puchase and can be bought from a Swagelok distributor (see swagelok.com). You'll want to purchase some additional ferrule sets for the fitting as those are not reuseable when you need to install a new TC.

People have been using Omega thermocouples (myself included) on DSMs since before Zeitronix existed. I don't know why you're so hung up on that one particular one.
You should really check out their catalog sometime. It's something like 8 or 9 hard bound books and weighs approximately 100lbs.

The two pieces together are equivalent to the Zeitronix probe. Both are type K thermocouples (indicated by the yellow lead wire and yellow connectors), and both attach to the manifold via a 1/8" NPT fitting. The Omega probe slides through the Swagelok fitting and is swaged to it just like a compression fitting. The ferrules cannot be reused, but they are at most $5 for a pack of 10.

Why even try to help at this point..... let him spend his money.
I've been running 12.0 -11.7 AFR's on E85 at 28 psi. My car only sees road racing use, so it gets driven hard, and only hard. I may bump up to 12.0 straight across.

You really just can't get through to some people....
My direct replacement for the Zeitronix probe will be here shortly.
I will post pictures and links for where anyone can buy this DIRECT replacement. Even has the 1/8"NPT fitting on it...
And the Swagelock fitting is for another probe that I have laying around... FYI..

Yes, I have all those books in my Office.. Good stuff there!!
Omega probes for EGT are amazing probes, you can configure them specifically to your applications for most of the time substantially cheaper than any "aftermarket automotive" branded one...
I can garantee you can make a probe that will be at LEAST 2x better than an off the shelf Zeitronics probe that will burn out on you in no time..
Plus they are really nice to deal with.
I recently ordered a 3/16" diameter grounded probe for my set-up that will handle over 2,000*F and will last me probably 2x longer than any other probe I have ever had so far..

Interesting thread. A nice mix of good info, heated debate (pun intended), and mild sexual innuendo. 
For another data point, I have been aiming for 11.8-12.0 A/F ratio on E-85. This is with the FP Red, 1250cc injectors, and single walbro (for now). I just threw in some FP4R cams, so I'll have some more tuning to do in the near future. And I may need to throw in the dual pump setup to see further gains.

Can't see the picture.
Edit: Assuming since I can't see the picture at work, can you post a picture of the probe with a ruler next to it so that I can see the exact measurements of it?
Once I get that I guess I am buying a second probe now from Omega.
