I'm Hay I have the chance to get a Neptune jr by apex with a better probe then factory and a pump and light box add on for 140 bucks is this worth it ?
While that is a good deal, I agree with going for the full Apex.
I bought the junior, and have spent almost as much as a full Apex to get it to where I want. Not to menion you are limited to 5 total expansions units with the JR, Apex is unlimited.
