Wow about time someone finally wrote this. Not saying teuf's isn't good but this has the name directly in it and it's a little more in depth.
Not to mention now with the z-board you can get the same speed as the Halo B, and the board can be found still for less then $40 bucks. Even it is were $40 it'd be the same speed and hold more balls.
So overall I would take an eggy over a halo anyday.
One thing to mention is when sanding down the Eggy II feed neck be very careful not to make it too tight of a fit, to the point where you have to twist it to get it into the feed neck of the marker. This will make the feedneck weak and eventually snap like mine did.
