Thanks Lynall and Doriz. The Mantech one also seems to get good reviews but it's dearer. I'll have a butchers at the Terrafirma one. Does the piston arrangement on the Britpart for the door work ok?
Thanks both I'll probably go for a LR/ Mantech one on flea bay. All seem to be around the £200 mark anyway. £500 a bit steep! Thanks again guys.
