I just did @ 60 of these... they are not bad after the first two or so. They are easier than the colored g3's. The only thing I did'nt like about them is the crt. it weighed 22 pounds. That's a lot of pounds of crt to get rid of.

It only took a small allen wrench, a cross tip driver in a drill, and a wire cutters.. around 10 minutes each
