Maybe the reason you can go in and pick up a Vectrix anytime is that not as many people are buying them.
From what I hear they're selling pretty well. Hoyt just has a better production setup. They've been around a heck of a long time and know how to produce product. Bowtech on the other hand is still quite young and they don't yet have the capabilities of a Hoyt sized company. Mark my words though Bowtech will be at the top in the next year or so.
