Colorado Services - Banks, Utilities, Telecom, etc... (Denver: credit, price)

[zenkonami]

After reading a thread on the Denver forum about Comcast vs Qwest for internet service, I thought it might be interesting to find out what other services Colorado residents approve and disapprove of. Who is giving you what they advertise? Who hides things in the fine print? Which services might as well be monopolies - and do they manage to serve you well at a reasonable price? Which ones give it to you straight and keep you happy (or at least content and well served)...and which ones always seem to be trying to get the better of you rather than provide you with what you're paying for?

I'm looking specifically for companies and services operating in Colorado, here. Any of those staples from banks, credit unions, telecoms, utilities, etc... Government run services are probably fair game as well.

Obviously mileage may vary, so I'm hoping for this to more of an opportunity to share with others your personal experiences with certain businesses rather than anything combative. (Mods please feel free to edit if any of this seems more problematic than practical.)
