Konica Labs will probably be cheaper I guess, since they are having a perpetual offer of 15 cents for 4R (T+C applies). For Fuji FDI labs, varies from lab to lab. Don't know about Kodak Express.
Agentmonkey - if you want to print at TripleD, I can bring you there this weekend, as I've some to do. Other labs, however, I can't help you.
