The sigma pump vacuum lifters are very good, but there’s no change out of £400 for a pair.
The small mechanical ones are not bad either, but I only use them for pieces that are too small for regular 8” ones. But they will work on a slightly textured surface.
But I’d still choose the larger type.
GGR Group have a decent range,
You can either go for something like this
Or alternatively, something like this, I have a few of these.
Woods are reasonable price at around £55 each.
These are also low marking.

These are specifically for glass, they have dedicated stone pads too.
These ones are decent all rounders I’ve found, but to be honest, lifted very little stone with them.
As we all know we work in a very dusty environment, so maintaining them is very important, always meticulously clean the surface of pad and whatever you’re lifting before using.
Regularly remove piston from handle, clean and oil the seal.
