Yes I always use cruise control on long trips and on the highway you'll find you save a lot when it comes to fuel consumption.
The other day i drove 300km on the N1 and only had to slow down to stop at toll booths, otherwise once you at speed and people are using the lanes correctly you don't need to touch and pedals.
I dunno about after market cruise controls, they probably make it but i dunno if i would trust it as I would a factory fitted device.
you also save a fortune on fines... just keep your cruise to just above the speed limit.
I also wouldn't get aftermarket.... it could go very badly.
