You can find better RO/DI systems in that price range, IMO.

I guess this one wouldnt be any good either.

If you go with anything other than the MaxCap system at the very least insist on several things:
1. A Dow Filmtec 75 GPD RO membrane, lots of units are being passed off as containing "Made in USA" membranes but do not tell you any thing about them. This should be a bright red flag saying "CAUTION, do not believe anything past this point". If they are too ashamed to tell you who made it, wah tthe manufacturers model number is and what ANSI/NSF ratings it has then pass on it.
2. A full sized 24 oz vertical DI canister and refillable cartridge. Many units use small horizontal tubes which just plain do not work as well as a properly designed cartridge. Horizontal tubes short circuit and channel often bypassing much of the resin. They also do not contain as much media which leads to poor contact time and short filter runs requireing more frequent replacements.
3. Properly sized name brand prefilters, often you see prefilters that do not even specify a micron rating. These are there to protect the most expensive part of the unit, the membrane.
4. Solid carbon blocks in a 1, 0.6 or 0.5 micron rating. You often see granular activated carbon in less expensive units which has an extremely short life plus passes carbon fines or dust on to the membrane shortening its life. Good carbon blocks can adsorb up to 20,000 gallons worth of normal chlorine residual and VOCs before exhaustion instead of 300 to maybe 1000 gallons with GAC.
RO/DI is not the place to skimp on quality, you will end up paying for it in the long run. Look at an RO/DI unit as a long term investment, it should easily last 10 years or more if it is maintained correctly. I view it as a tool and if I am depending on a tool I don't buy it at Harbor Freight.

Just the difference of 1 or 2% difference in RO membrane rejection rate can double your di replacement cost and in the end cost your more to run.
The fact that the original link mentions nothing on the rejection rate nor even what brand of membrane makes me very suspect.
Before purchasing I'd for sure inquire on that and make sure it is a good quality membrane with high rejection rate. I'm banking that is subpar membrane or else they would have been more specific than using "name brand".
Retail price $659 all for $95 ? Where we born yesterday ?
