Which RO unit should I purchase?

Hello RIU I'm currently comparing 2 RO units and trying to decide which one to buy this is a lot of money for me so I want to make sure I get the right unit here are the 2 units I'm comparing the first is the hydrologic small boy De-chlorinator and sediment filter. http://www.greners.com/i/hydroponics/components/water-filters/small-boy-de-chlorinator-and-sediment-filter.html The second is the hydrologic stealth ro 100. http://www.greners.com/i/hydroponics/components/water-filters/stealth-reverse-osmosis-filters-ro100.html Which one do you think I should buy? The small boy has a much better price point and is available from my local hydro shop but will the water it produces be pure enough for my soiless coco grow? I'm on a well so the water is really hard.

Bought a Britta for under the sink

A little more information on your personal needs would help. How many gallons a week do you need. Personally I don't use RO any more, due to the amount of waste water. I had waste doing to one garbage can and RO a couple 5 gallon buckets. Instead I found a 65 gallon rain catch barrel and only the last few months have been using that. When it's full transfer into something like a garbage can.

rain water ?

I need mabey 60 gallons a week this is my first time doing a soiless coco grow I've always grown organic I'm going to have 12 plants in 5 gallon pots of coco and perlite it will be a drain to waste system and I will be hand watering I'm guessing 60 gallons a week would be sufficient. I'm really just wondering what the major difference between the two systems. Is the small boy actually an ro unit like the stealth 100?

just saying coco-hard water maybe not so bad

I've had the RO100 for over 4 years and I still love it. Worth every penny.

My tap is 190-200ppm
I used to run ROwater had to give it CalMg supplement. Since using tap water at proper ph I need no CalMg anymore. Just saying sometimes it's no nesecary. Depends on your water supply.

I also used to run the ro 100 takes forever to fill up a 5 gal bucket but the water always came out ultra pure I think I'll get another ro 100 the small boy is cheaper but I guess the ro 100 is worth the extra cash
