So I have been looking around for a apex jr for a while and stumbled across my LFS selling one without display or temp probe for 75$. I decided to pick it up. First question, am I losing money on this deal? Second question, can I set this up without a display? And last question, can I connect it to another setup as if it was an EB4 if I was to go that route? Any help will be awesome!

. It used to be 4 + display which often got misconstrued and stated as simply 5.
for a long time marine depot still have the pictures of the black apex
