The cosmetics certainly soak up the cash, and while restoring back to original is all very well, I'd prefer producing a rough looking but reliable, useable machine that would be back in use quicker and cheaper.

Ain't that the truth.
All depends what we want to do with thing afterwards I guess.
If you want a daily rider, then the cosmetic investment isn't a good plan as the deterioration in daily use will cause you pain every time it rains. Need to be obsessive compulsive about spit and polish to keep a daily rider looking good. I'm not the least bothered: one of mine is about to get its 4th oil change since last November.
If a beast is for occasional use, or a show pony, then yup, go for it - while the money lasts! Bearing in mind the value of the finished result will probably be only half the investment (if that matters) and that the difference in values between machines with patina and a track record of reliable regular use as compared to little-used and shiny isn't what it was. (More because 'shiny' prices are down rather than scruffy ones being up, although 'original' in decent working order has its own premium.)
We're a broad church luckily. Sometimes I see a friend who says 'Bill, you do actually have a couple of shinies, so why do you insist on using scruffy ones and why don't you smarten them up?' To which I say 'Because I like them' and, more to the point, 'How often do you see them break down?'
