Hope they're better than the SA Angels. Half of these angels orgs function like cabals.
The biggest problem is not valuations, but cat herding. As soon as you put a dozen grey hairs in a room you will end up with 13 different opinions. This can make progress a lot slower than it should be.
On the positive we have a partnership with VC fund (SA SideCar) that matches investments by the angels 1:1 with no extra extra due diligence. They automatically follow on in later rounds which is really a massive positive.
