Has anyone fitted one of these new-fangled aluminium core / plastic tank radiators to 300tdi Defenders? Cost of recoring brass / copper radiators has become higher than a brand new aluminium / plastic radiator and local suppliers have recently started to supply said aluminium / plastic radiators. I am a little bit apprehensive. Any thoughts? Furthermore, on ebay, prices vary between £79 and £130. Can anyone point me in the right direction? I would naturally be tempted to purchase one that costs somewhere in the middle of the range but would like to know which to go for and which to avoid.
