As I found out... The drill bit tended to slip in the chuck (it's=20

Hopefully it didn't damage the chuck...

It's pretty rare to see drill bits with a flattened shank around here.=20
The vast majority are round -- even the PCB drills.

Oh, too right. Before I got the Dremel, I used to drill PCBs with an=20

Point taken. I did notice that even the likes of Axminster Tools were=20

price.

Yes, it's complete, yes it works, yes it's the "genuine article" (at=20

LOL! So the scammers used the address of a major newspaper in Seattle?
IME, they usually use addresses which just plain don't exist...

I don't think I've ever seen a Rotozip tool in any of the local shops...=20
they seem a bit thin on the ground outside of the USA...

I don't have a router -- what I have are a couple of 2mm=20
tungsten-carbide PCB router bits which just happen to fit the Dremel.

I wish we had shows like that on TV... closest we get to that is=20
"Changing Rooms" or "Grand Designs". Neither of which is even remotely=20

And then there's X Factor and American Idol... I wish ITV would just=20
