Having read this thread a while back I have just received my first set of prints from DSCL.
I turned to online photo processors as Boots don't offer 9X6 or 12x8 prints and the local camera shops manages to get a yellow tint to everything I take in.
I am impressed, very good quality, no visible banding on areas of bokeh which unfortunately a local online photo processor managed to produce.
It was a bit of a faff trying to calibrate my monitor but the profiles they supply pretty much match the prints I got back, so I must have got it close.
Oh, and they are pretty quick too.
