I've personally been waiting for the SU-233, now it's coming!
Element internals are not worth it, because of tolerances, but so far for their externals and accessories (553, Surefire, etc) I've got, I'm totally satisfied.
This SU233 is a definite buy for me, and if they update their PEQ-15 to work with that switch I'll probably get one too.
As it's not shown on the pic, I just hope they will come with the Insight military SU233 stickers!
