That's interesting. I don't (as far as I know) need then, but the reason I asked was that David Askew *was* going to get tooled up to 4200 skyhook, and the cost was prohibitive.
I've found the chaps in Ireland are doing exchange refurb at £371 assuming yours can be refurbed, otherwise there's a £75 extra.
That's not bad, compared to new
