Racetech gauges any good?

Hi all
I'm thinking of fitting gauges to keep an eye on oil temp/oil pressure and possibly other things in my 182 track car and come across these bad boys with a lovely opening ceremony see vid.

however i have come across these which looks the same but abit cheaper so im wondering that one company is charging extra on the same product.

Has anybody used them and are they any good/accurate as i don't want to end up with cheap crap but i dont want to spend a fortune ether.

thanks
