Hilditch have had a few through but for some reason the 5008's are only fetching about £500-£520 each compared with the much older 4008's which are still going through at between £1000-£1500 with the lowest fetching £800.
My contact there is Neil Saint on ext.251 if you need any help.
Hope that helps.
We decided to keep our old 5008s for cannibalisation instead of auction as we were told they go for £100-500 normally.
4008s sell much better because they can be used abroad with non FMC lines and other disposables and you don't need a service card or laptop to service/fault find.
Using the old screens and other less critical parts has saved £1000s over the last couple of years - although I wish I didn't need to.
p.s. I have used Hilditch and they have been pretty good, but BMA are also very good.
