i spoke to him John about inline heaters. He said he has worked on so many over the years - all the Ashbys and Magma's etc and he has engineered a much better one that gives constant heat. Certainly looks impressive - they come without heat control but for about an extra £50 he can put in a thermo. I spoke to a couple of guys who had them and said they have had no probs and he said if you have any problems you just take it in and he sorts it but with him being in London and i am Midlands i bottled buying one. I think they are about £600 - they look like a beast if they are reliable.
