why not loose gravel ?
you can put those plastic grids down first to hold it in place as well.
pros
cheap
quick
cons
probably going to end up with gravel everywhere, I suppose this can be combatted by using slightly larger 20 - 40mm gravel ?
We've got "un-gridded" loose gravel / stones for the majority of our drive.
One downside is retrieving a good chunk of the drive from the lane once Mrs Chri5's mother's has visited us. Can be a pain for weeds but I find a good application of weedkiller from a watering can helps control that. Weeds are also quite easy to remove by hand if a few sneak up.
We've also got a pedestrian path up the drive which is block paved (plus more at the top of the garden). Removing the weeds from that is much more fiddly than the loose gravel.
I'd probably look at the resin bonded stuff if we want to replace the gravel.
