I need a some holesaw bits . Preferably a little kit with different sizes.

Mainly for ceilings for downlights / spotlights etc

These are excellent. They are really quick, stay sharp for ages and it's really easy to get the discs of plasterboard or other material out of them. Definitely worth the initial cost if you're planning on doing a lot of down lights: Starrett KMP11021 General Purpose 11pc TCT MPH Holesaw Kit - PowerToolMate - https://www.powertoolmate.co.uk/powertool-accessories/holesaws-and-accessories/starrett-kmp11021-general-purpose-11pc-tct-mph-holesaw-kit.htm?opt=9052&gad_source=1&gclid=CjwKCAiApsm7BhBZEiwAvIu2XwuqGbx-U7LRwBiyiYDW5F7w9ikZlM7pa6GO7x3w0RY4tTSxhBqQvhoCxSIQAvD_BwE

Carbide holesaws are expensive but they're a revelation in drilling. I find the old style with lots of teeth (but still carbide tipped) better suited to ceilings though - the big tooth designs can be quite savage especially in larger sizes (but great and unbelievably fast on wood and other stuff)

I've even changed most of my dont-use-often-enough-to-justify holesaw sizes as once you're acquainted with carbide going back to bimetal or hss is like getting on ryanair after flying concorde

I have the set in mainline's link, two other sets similar in design to the normal hole saws we use and a carbide set. Still rarely have the specified size for the downlights I'm fitting.
Don't find the carbide ones to be of any great advantage for just drilling plasterboard, since a HSS one with the teeth almost disappeared will still work OK on that stuff.
The specified hole size for most downlights includes a few mm to clear the fixing springs, so you can usually get away with a hole a few mm smaller than specifies, if you use a padsaw to open out a bit where the springs are.

I totally agree with you, I've had that type of set for years and as you say not the proper sizes but will do the job at very little outlay and saves using the decent ones.

Didn't Concorde cost an arm and a leg for tickets and ended up crashing, killing over a 100 people.

You will find this very useful for the ceilings.

Didn't Concorde cost an arm and a leg for tickets and ended up crashing, killing over a 100 people.

Only because another aircraft left a big lump of metal on the runway due to poor maintenance - combined with other factors.
As far as I recall, that's been the only Concorde fatal crash. While looking up, I found this http://www.concordesst.com/accident/past.html where it lists a number of burst tyres - so it certainly seems like AF4950 was somewhat unlucky Air France Flight 4590 - Wikipedia - https://en.wikipedia.org/wiki/Air_France_Flight_4590
One of those "wish I'd done that when it was possible" things on my list was seeing Concorde flying, even the "stand outside the fence at the departure end of the runway for the whole body effect" bit.

On the other hand, Boing designed an aircraft which in hindsight seemed designed to fly itself into the ground under common and forseeable fault situations Boeing 737 MAX groundings - Wikipedia - https://en.wikipedia.org/wiki/Boeing_737_MAX_groundings

As to costs, at one time BA used Concorde as a marketing tool - things like "fly ten times business class and we'll give you a trip on Concorde". Otherwise, yes tickets were quite expensive.
I've looked round the static exhibit at Duxford (one of the prototypes). It's "snug" inside. So while it may have been quicker, I very much doubt it was more comfortable than (say) business class in a 747 or A380, other than enduring the discomfort for a shorter time.
