Sounds like you've got a lot of anger built up against him.
I'm not defending nor attacking MRL, not my place too.
That said,i was burnt by a shop that had been in business nearly 35 years and had a great rep locally. That shop destroyed my 440 block and pretty much told me to shove it. So I don't think we can go by length of time in the business either. It's almost like playing Russian Roulette but instead of there being just one loaded round, there's 5.
