You can have two females that get along and you can get a male and not have eggs- it all depends on the birds personalities. Either way, you have to be prepared to house them on their own forever, should they not get on.
Also bear in mind that Ace's relationship to you may change with a new budgie friend. Not in a bad way, but likely she'll be more interested in her budgie mate than you, but she could also encourage the new budgie to see you as well
