I've never really seen inkjet output that appealed to me--except maybe quad black on heavy rag paper--and I've got enough cantankerous machinery in my life.
For quick prints I go to Target.
For decent quality and a wider range of papers I use mpix, ofoto or ezprints, depending on who has the better pricing and fit to the media and sizes I want that day.
For the stuff where my original has more resolution than the mass market online places provide I get 400dpi Lightjet output from
www.reedphoto.com in Denver.
I keep meaning to try the quad black piezography prints from West Coast Imaging. I really like their samples, but haven't gotten around to it yet.
I also keep meaning to try the digital to b&w fiber paper via Durst Lambda from
http://elevatordigital.ca/ but they're seriously expensive--$40 for an 8x10. I mean, it makes sense they're expensive, archival processing of fiber paper is a lot of trouble, but sheesh...
All of these (except the untried piezography from WCI) are traditional light-exposed paper processes.
