Started my SE last night
I always hated kits until I built my SE. I'm the worst builder in the world, but Sig kits make you look good. My planes always come out heavy, but I was impressed on how light my SE ended up.
If you follow their suggestion, you can truly build it as fast as you can put pieces together. I went from a box of sticks to the first flight in 26 hours, spread over 3 days. I was impressed.
By the way, if you hinge the ailerons so you have 180* of movement, you can do some wicked manuevers.
