Welcome Dan - I am UK based too, (Hampshire, although from Fulham) and I cannot recommend PT highly enough. He will answer any stream of questions and reply within 24 hrs. He also does a QC check before despatch. I haven't yet tried any other dealers, but if they are on this forum, you can guarantee that they will be reliable.
