Not an expert in C/L my self, but as I see it the LA 40 is cheaper than the Brodak the last time I checked. It has a lot more power than the Fox, unless you hop up the Fox with ABC sleeve, hemi head, and stuffer back plate. Even then it has a bit more power. I think it is also easy to modify the timing, but don't know how. After paying some one to fix the timing the Brodak costs less, but I don't which is more powerfull. For most sport flyers the LA works fine out of the box.
