repop rallye dash tachs (are these any good)?

Repop rallye dash tachometers, are these any good?

I am not looking for shitty assed comments about how they are made in Chinna. Most of the repop stuff is Chinna , or Taiwan.

What i am looking for is actual user experience with one of these. Good, bad, or otherwise.

I am not interested in paying ridiculous cash for a 45 year old tach that i got to spend even more cash to get restored. Id concider that only if this was a numbers matching formula S or something like that, however this car is just going to be a nice driver, weekend cruiser.

And NO im not cheap, i spend quite a bit on my projects, just wondering thru actual experience of those who bought these if they are any good, or is it a buyer beware hit and miss.

Thanks
Matt
