Burner is fairly expensive, and as you noted, it STINKS! Chopping is great if you can get the hang of it, but precuts are uniform, have a variety of shapes, and are easily obtained if you need to refletch with the same cut. However, there is an alternative....
Have you ever tried cutting fletches out with scissors? You can make a template out of the lid of an old coffee can, and cut as amny as you like. It's pretty easy once you get the hang of it, and it's even easier if you put a strip of fletching tape along the quill to hold everything together while you cut.
