I don't really know prices of DATs, but that price of $1200 seems a little steep to me. You could score a NJB3 for $139 (mine was $160 shipped), a UA-5 (no oade mods) for $300, leaving about $540 for mics, stand, cables, etc.
I found a good stand on ebay for less than $30. For beginning, you don't need the most righteous cables either. add a T-Bar, battery setup for the UA-5 (mine was about $60 to make...) - and you still have enough money left over to get a set of mics that are nicer than octavas.
And this is for new/refurb stuff...
