The AlphaTec is at least 6 if not 7 years old (before the hybrid cam and a half came along)

Take the advice of Mikey S. and check in the AT classifieds. I am sure you will find something to your liking. As for the Hoyt bows, they are a top quality bow. I have shot nothing buy Hoyt for the last 5 years (6 new bows) and couldn't be happier.

For a beginner, I would try to stick with a bow that has a longer axle to axle (36" or more) and one that has a brace height of at least 7". This should give you a bow that is pretty easy to shoot.
The rage right now seems to be these ultra short bows (33" or less). I can tell you from personal experience that the shorter bows tend to be more critical of the shooter than a longer bow (all other things being equal).
Something like a Trykon XL, Vectrix XL, UltraTec or ProTec would be good choices.

Stay away from the 03 UltraTec! The risers were weak and had a tendancy to bend (I know of more than 4 cases of this happening). The problem was corrected in 04 and things have been fine since then.
