A A1200 may cost you more than other low end Amiga (unless you are in Europe) I would get a A2000 for the BBS, great workhorse and cheaper than a A3000.
No the A1200 does not have a VGA port. Actually no other Amiga has that built in! You can use a VGA monitor for limited WB support with the DblNTSC and Productivity modes but not for games. You will need the Amiga to VGA adaptor, they sell on ebay all the time.
