For the past six years or so I have been sending all my color work (Kodachrome, subsequently Ekatchrome) via UPS/Fedex to Dwayne's Photo of Parsons, KS. Their prices are competitive and their work has been consistent from day one; I have yet to experience any lab screwups. Accordingly, for any E6 work, I can give them an unqualified recommendation. As far as black and white goes, I cannot offer any suggestions. I have never been satisfied with b&w machine processing so I have almost always done my own b&w work (souping and printing, 35mm, 2 1/4 and 4x5).
