Question Simple RO system that you love

I have very hard water. My GH and TDS out of the tap are always super high with a pH of around 7.8.
Long story short, I have decided to cut my water with some RO and also use it for top offs. I have been buying RO water from the grocery store, but I am thinking it would be cheaper to just get a system at home. Here is what I am looking for....

I would like a system that I can hook up to my sink or hose and create maybe 5-10 gallons of water and then put it away. I do not want to install anything if at all possible and I don't need to make a ton of water. So my questions is this... Who has a portable RO system that they love (and preferably didn't cost $200)? I am not super handy so simple is good too. There are several options on Amazon and I just don't know where to start. I know sometimes cheaper units have a more expensive ongoing cost with more pricey replacement filters etc, so if you can tell me your experience with that as well, that would help.

Any real life feedback on the brand/model you love would be appreciated.
Thanks in advance!

Something to think about--small RO systems make about 2-3 gallons of water per hour, so you are looking at 2-5 hours of having to babysit and prevent your storage container from overflowing.

I have a permanently installed under-the-sink model with a 5-gallon storage tank and auto shutoff, and couldn't be happier.

You could get a great setup for under $150 from some sellers on fleabay.

I keep my 6-stage system at home stashed beneath my bathroom sink. Doesn't take up much room at all. When I use it, I merely pull out a rigid tube to attach to my faucet adapter (which I leave on), put the tube for waste water near a drain and the outflow tube into my container. Maybe a one-minute setup whenever I use it once per month. I just fill up a couple Brute cans that I have hidden out of the way.

When I'm finished, it only takes a minute to put the tubes back under the sink.

In addition to tank stuff, RO/DI water comes in extremely handy for houseplants and general gardening, for misting purposes and making household cleaning solutions.

That can be easily automated so you don't have to babysit anything. With my old reef tank I had my rodi making 10g of water for top off per week and it was completely automated. When the container got to a specific low level it would turn on my rodi system and stop it when full.

Thank you for the feedback so far. Any brands you suggest or think I should avoid? Also anyone try to go cheep and regret it? I would rather by one and spend more if the cheap ones need replacing often, but if I can get the job done and spend less that would, of course, be ideal.

Skip the cheap ones if you have chlorine or especially chloramine. A long dwell time is required for their removal by carbon. Very little is removed by the membrane which is also damaged by chlorine.
