I'll have to say CO even though I'm a DL junkie. I'm not exposed to them in my home market - ATL but they appear to have a very good reputation with thier faithful. I can also recall reading several postive articles about CO in newspapers and other publications over the past several years. From what I've heard and read they have an excellent product in terms of service, fleet, employees, ect. Considering the past 8 or 10 years have been the dark ages for the LLCs, I think CO has come thru pretty well.
