Photo Lab Near Waterloo, IA? E-6, C-41 + real B+W

I have a friend who lives in rural Nashua, IA, near Charles City, IA,

and makes regular trips to Waterloo [nearest large urban population, I

assume...]. I'm looking for suggestions for fair priced, good quality

labs.

As a caveat, she worked with Porter's on a few occasions and was not

happy with the quality or service of their processing.

Can somone make a suggestion? I'm open to providing her reasonable

mail order options, as well. I already know about A&I.

Thanks.
