I have heard they have gone up in price.
I needed one cos I took mine out to clean the oil out of it as you do when you have a Disco 2,
and as the plugs were so stiff I managed to drop it on a gravel drive. After that it didn't want to know.
so I took it an allegedly expert bunch in Poole to have it mended only to discover, through research on the net, that they were a bunch of cowboys. thankfully I took it off them before they did anything with it. I still have it and I sent it, via my son in law, to a clever lady engineer who uses a microscope to find breaks on PCBs etc. she couldn't find anything, which is a shame as it is chipped and I'd like to still be running it.
so if you do send it away, I'm sure you will send it to peeps who are honest and reliable. Might as well take the chance to get it chipped, if you are so inclined.
Alive tuning repair for £200 or replacements can be as much as £750
