EGT gauge

[layback40]

Often various members talk about concerns about damage to motors, especially if turbo-ing a n/a.
I have a JD tractor that was turboed about 20 years ago. It was done properly, new valves/oil pump/pistons/ bigger oil cooler etc. It had a EGT gauge on it & you could see the temp rise when it was working. The gauge eventually vibrated to pieces. I was quoted over $100 for a replacement gauge.
A friend suggested a cheap Chinese on on ebay. After a bit of drama they let me bid on it ( they had a block on bids from Australia).
I got it for a few $$.
Has any one had any experience with these?
If it turns out to be any good, I will let every one know. They have a number of them as buy it now for a shade over $20. This is the item number on ebay.

Foot note;
While I realize that our site is sponsored by the buyparts, I dont believe that this is in competition with them. I am more interested in finding out if any one has used one.
