I got my lights from shiningbeam after ordering them 5/25 (I'm not too far from Brooklyn). I went with lights that can use AA batteries (RC-C6 II Q5 with extension tube and C-N3 II R4).

You can get an extension tube for the smaller light (RC-C6 II) that lets you use 2 AA batteries for $3.5 from shining beam. (Note that, with the 2 AA lights which also support the CR123A battery, you might want to shim-out the first AA battery, with duct-tape or o-rings, so it doesn't shake.)

Note that the RC-C6 II and RC-N3 II lights do not have the strobe mode (the RC-C8 II light has a strobe). Having a strobe is a useful option.

This is nice. If you want flood, the adjustable focus lights (RC-C8 II and RC-C6 II) give a wide and even beam pattern (the "thrower" mode for these lights is peculiar because it projects an image of the LED die).
