The issue with SAMs has finally been resolved.
It seems as though the original print was dispatched but never arrived. My email enquiring about it was then missed.
David offered me a reprint free of charge, which arrived today.
After all that I must say I'm very happy with the print received. I sent the same image as a test to DSCL and SAMs. The DSCL print arrived two days later, was well packed and looked excellent, colour matching was good, as was the quality, although the paper was a little flimsy, but this wouldn't be an issue once mounted.
After comparing the two prints I would say that SAMs just has the edge. The colour matching on both were pretty much the same, but I would say that SAMs was just that bit sharper. Also the paper was thicker giving it just that bit more quality. Both came flat packed with DSCL packing being better.
Overall you wouldn't go far wrong with either of these labs, despite the issues with SAMs hopefully it was a one off.
Hope this helps
