Mine is the ARB CKMA12.
I used to use cheaper ones (various brands) to keep cost down but they kept packing up. Decided it would be cheaper in the long run to get a dust proof, heat proof, water proof one and never looked back. No issues, compact and neat, and reliable as hell. Highly recommend. Especially as I previously mounted in the engine bay of 4.0 V8 Disco II that gets EXTREMELY hot under the bonnet.
It wasn't so much $$$'s to burn, but reliability and build quality.
I too had a Bushranger comp once, managed 7 tyres and spat the dummy. They didn't want to know about warranty, they reckoned I must have been "over using it"!
