Ducati parts bin starter on my 696, gutted

So as directed by you kind gentlefolk I have started a separate post on this issue. Went to start up the bike for the first ride of the year and bike wouldn't turn over. Checked the power all the way down to the starter and all looked fine. Battery is healthy. Had the starter removed and disassembled and this is what has been reported...

'there are 3 faults with the starter, the oil seal to protect it from the engine oil has gone, one of the brushes has lost connection from the brush wiring, also the rotor is so worn to the point its the worst wear I have ever seen. As soon as I had opened it there was the distinctive smell of burnt electrics, there is no repair possible with this unit..'

The bike has done 5k miles in 6 years mostly 50-100 mile weekend runs, garaged it's whole life and pampered where possible, service every year regardless of mileage, only drinks unleaded super etc, etc. You get the picture.

I'm now faced with a parts bill of £370. I don't know why this has happened nor if it will happen again if I throw £500+ at it? Someone suggested West Country Windings any opinions? Perhaps someone can recommend a breaker that might have a sound unit?

I'll try to get a picture up, laptop has developed a random fault and can't upload on the phone. Grrr
