In the SIGs take a good look at the Kavalier, I have built several of them for club members for a racing class, nice build and great flying plane!!
Blue Jay has kept the prices down and cut a great kit. I'm a Kaos guy myself but after building and flying the Dirty Birdy I feel it is even more stable then the Kaos, does a much smoother knife edge too!! It has instructions for all three types of landing gear too.. Mine was a tail dragger. Blue Jay is keeping the Bridi designs alive and well but these are mor builders kits and a bit harder then SIG or GP. Just something to keep in mind.
