McMaster-Carr has some good reinforced vinyl hose that holds up. Get the stuff with the polyester braid, it resists kinking way better than the cheap stuff. Just make sure you match the inside diameter of your old line.

That "pang of regret" is why my garden is full of weird plants now.

Honestly I was the same way, always making a fresh pot. Then I started working from home and wasting coffee felt stupid. Now I microwave my afternoon cup every single day. It tastes fine and I'm not pouring money down the drain. Changed my whole view on it.
