I can concur that the Sig 4*40 is now lazer cut. The only problem that I had with the plane was that the spar cutouts in the ribs were a little loose. I laminated some very small pieces of 1/64" plywood in there. Works like a champ.

IMHO, you'd be wise to get a 4*40 before the SE. I have one and love it. It's a blast to fly. Will fly almost vertically with a TT Pro 40. The plane is just plain fun.

I can't wait to get my SE finished, don't get me wrong. Along with a nice, easy transition plane between a trainer and the SE, the 4*40 is just a lot of fun to fly.

Hope this helps.
