The 24T is probably OK but they're a little out of my price range at £125.00 (though It's reassuring to see that they are available).
The one that caught my eye is this one:https://spacycles.co.uk/m2b0s109p2000/S ... e-Chainset
It's a 28T but the price and quality is what I'm looking for. I would snap one up if it had a 22T small chainring (needs 64 BCD I presume but could take a 24T?). Another option is to buy the crank/spider and build it up but Spa are limited AFAICS to 74 BCD.
However all this is academic if it isn't clear if all the Spa chainsets are really OK for 9 speed:
To add my experiences here, I tried to use the Spa Cycles triple, Sugino XD-derived which I believe was originally designed for use with 7- or 8-speed, with a 9-speed chain and had issues with the chain getting stuck between 'rings and slipping - loss of drive
I really like the idea of Spa carrying on with these chainsets while everyone disappears into outer space with ten and eleven speed, octalink and Lord knows what. But this has left me a bit unsure now.
I don't understand why you think that Spa would sell stuff that doesn't work?
(OK, there is one person reporting a problem with a really cheap (£25?) chainset (steel/alloy rings) that chainset is no longer available and I don't know if it was sold at the time as suitable for 9 speed or not. I do know we sold lots of them, and they didn't all come back.
Against that you have 4 people reporting their stuff works.
You won't get custom rings on a £35 chainset.
You don't have to pay £125 you have picked the most expensive one....with TA rings.
This one [urlhttps://spacycles.co.uk/m2b0s109p3052/SPA-CYCLES-TD-2-Touring-Triple-Chainset-with-Zicral-Rings][/url] is a lot of chainset for £78; and its one Spa use on their own bike builds, eg. Wayfarer.
But until you try your existing 8 speed chainset and chain, 9 speed cassette and rear mech. you don't even know if you need a new chainset.
