Need major help on bow decision.

As of right now I have a high country sniper. Bottomline it kills but I feel like it is a little slow. Last year I shot a deer that was thirt-five yards away. The deer reacted to the noice from my release but the time the arrow hit. I got lucky and still managed to get a lunge. I'm in college now and not made of money. There is a bow for sale only $60 dollars with an extra string and cable. Myself or the sller know anything alot about the bow and I figured someone here could help me out to decide whether this bow would be much better, faster than my older bow. Any feedback is appreciated about either bow.

Here is the bow i'm interested in.

Hoyt protec Bow
