This I can agree with wholeheartedly!
I run my business pretty close to a trunk slammer...

Not really, but I do work full time and run my company part time, but I spent about 200 hours last year simply correcting $100,000+ installations to make them work properly. Not joking at all... I was paid about $20,000 to correct the work of another installer to simply recable and rewire and 'FIX' was should never have been broken to begin with.
Even then, I still ran into a brick wall with the system due to the extremely poor infrastructure established.
The quality of the gear does not reflect the quality of the installer, which is why there should never be any issue asking for references or getting them quickly. It certainly isn't my advertising which has gotten me work, but the good word of references and happy customers.
