i dunno, Dlask might be great stuff, but if you don't NEED a custom gun then there's a handful of choices with lower cash outlay and much less waiting around.
so, ya, $1200 is too much if $800 will work just as well and meets your requirements. that $400 diff can get you 1,500 rounds of 9mm ammo fairly comfortably (SFRC). but that's just me, and i don't particularly enjoy wasting money or overpaying for anything.
