In my opinion and limited experience a scope with an equatorial mount would be a nightmare to use as a balcony scope. I'm just another newbie so don't place too much emphasis on my opinion, but given your requirements a refractor might be a better option, a couple of suggestions which should be within your budget
Skywatcher BK909AZ3 or
Skywatcher BK1025AZ3, though some more experienced members may want to chime in. Regardless, you'd really be better served by something on a reasonable Alt-az mount given what you want to do, it'll be a lot less frustrating.
