Appreciate light hearted banter.
Have a rough idea cost of re-tube will cost in excess £1500+, notwithstanding fuel, time & inconvenience of delivering rib dahn sahff.......just wondered if inserting 'inners' at a cost in region of c£300 would viably extend an old ribs life by a few years while I save up for dream machine?
