which scope to get

I'm looking to buy my first real scope. I've narrowed it down to 3:

Antares 119GP Refractor:
-----------------------
-Research Grade lens
-Diameter: 93mm, Focal Length: 1000mm
-Multi-coated Research Grade achromatic objective lens
-Aluminum Tube
-Optical tube assembly, mount rings
-1.25"-32mm Plossl, 9mm Plossl, 2X Barlow
-1.25" mirror star diagonal
-6 X30mm finder scope
-2" rack and pinion focuser
-2" to 1.25" adaptor
-EQ3-2 mount

Antares 515 EQ3-2
-----------------
6" Newtonian Reflector (750mm F/5,1/10 Wave Parabolic mirror) with EQ
3-2 Mount ,1.25" Plossl eyepieces 32mm &9mm, 2X Barlow lense and a
9X50 mm finder scope.No photo available.

Orion 'long tube' 150 x 1200mm reflector (f/8)
----------------------------------------------

I live in the suburbs, and right now light pollution in my yard is not
bad at all, but in about a year a shopping plaza will be built
adjacent to it...probably HPS lights will be on all night...it'll
probably be bad.

I like planetary and deep-sky. I'll be observing solely from my back
yard.

Off-centre sharpness (coma) of the reflectors is a concern for me, as
is collimation (never did it before). I like the idea of the f/8
Orion. Do reflector mirrors need re-aluminizing, or do modern mirrors
not need it? Which is best for me? Thanks.
