interesting alternative to a scottoiler

[simonm]

Used scottoiler £30, litre of cheap oil £4, can of degreaser for the mess it makes £5. There you go, 10,000 miles of chain lubing for less than 40 quid!

I only said it was interesting, not a must have ;-).  It was mentioned in ride this month as some Norwegian bloke had one.  I was curious about it.  It's an interesting concept if nothing else.
