Being a coffee lover – my other half bought me a filter machine as a birthday pressie a few years back.
After a few uses, the machine went back in the box, never to be used again.
The reason for this is that it took too much time & trouble to make a cup, compared with instant coffee.
I happen to like the taste of instant coffee – so these machines cannot compete. Although there is a difference in flavour between instant coffee brands – with two heaped spoon-fulls in a mug, I have found any instant coffee will do.
My advice would be to ensure that you like the taste of the coffee produced by your chosen machine. Just because your new machine is using Kenco Rich, it will not be the same as the instant version (otherwise why spend £75 on the machine).
