No offense but maybe you should research it more before you decide. There are no "right" blowers... only varying opinions. Both kits you mentioned are good but each has its own strength/weakness. I recommend reading these articles first. There are other informative sites out there as well. Get a good understanding of what your options are based on what you want.
