Horton makes some great crossbows along with a few other company's. I personally would rather use my compound than a crossbow. Alot of folks never shot a xbow and are misinformed of its capibilities. They think its a silent rifle...not the case. Generally xbows are ALOT louder than a regular bow, they are usally (unless you buy a really good one) slower than todays compounds and produce less KE. They are heavier and more akward to carry and manuver in the stand.
The only plus side to a xbow (IMO) is the fact that you don't have to pull it back when the deer approaches, like a regular bow. You are still limited to one shot and usally around the same distances.
My opinion...if your physically able to draw and shoot a compound...I wouldn't bother spending the extra money for a xbow.
