I would rate Lion as the best in their field. Their service is very good but I have had issues with quality on some of the mouldings I have received. I guess that's ultimately down to the manufacturers but perhaps closer checking on packing would save the annoyance of running short of frame because of surface faults or (on two) occasions a warped length of moulding - only discovered on assembly. To be fair, Lion have replaced faulty stock in the past without quibble. The Lion website is excellent and very nice to navigate, it leaves their competitors very much in the shade. Their prices are very competitive too.
