Phoenix analytical are cheaper give more results, I've read on here there are a few things Murphy's don't cover, and are more reliable IMO.Have you considered getting some of the Salifert testing kits? They won't tell you everything but they are quite straightforward and fun to do... I have the Ca and KH/Alk ones which agree well with my water report.
Alternately for the princely sum of £35, Murphy and Sons will do you a full brewers analysis with suggestions on how to correct for various styles... well worth it in my opinion
