Dunno if this was already posted, but I have been testing the new EVA construction, aaaand I found it lacking (compared to KIS).
1) It can't deal with "heavy objects" in a celestial body (like Duna). While it makes sense, it also does KIS, requiring more nearby kerbals to do the job and actually doing it.
2) The parts you can store are few.
3) An EVA constructed sat will NOT fulfill contracts (won't check the "build a new unmanned blahblah"). Same as KIS, to be truthful.
4) Storage options are scarce.
It's in the right direction, but still lacking
