Search Ebay for EGT, there's a guy who sells a digital one. Just upgrade to the better thermocouple that they offer. Reacts extremely fast and its digital accurate.

google auber instruments and you get their website.
lots of good stuff there, I have an EGT and Boost from them.
best part is that they have two alarms that you can set the trigger points for that can be used to switch other things(trigger water meth based on EGT anyone?)
