I personnally would only buy from an archery dealer. These things have to be tuned and they are subject to breakage. I broke a limb and the accu-draw. Dealer had me hunting in 2 days. Lifetime warranty.
I would get a lower end model from ten - point such as the Titan then get a high end model from a lesser company. Horton is a good product.
Remember you have to cock these things and they cannot be misaligned when fully drawn. Thats why a cocking device is so critical. These things are super accurate if all pieces are in the right place.
Kinda like a muzzle loader.
Couple things about a crossbow. They are heavy and hard to carry,noisy and being horizontal you cannot get close to a tree as the limbs/ string will hit it. Big advantage is you don't have to pull it back when a deer is present ,also they are far more forgiving when excitement kicks in as you can shoot sitting or use a rest.
