There are lots of cheaper and perfectly serviceable crossbows on the market, but I've always been a Tenpoint fan. I've used them hard for many years, their service and support is amazing and I have always liked the fit and finish of them. I recently bought a Stealth NXT because I wanted something fast, narrow and totally quiet to cock and I have been blown away by it.

in general there are three brands that will come up consistently as top quality and performance

Tenpoint
Ravin
Excalibur

all are top build quality and all are made in USA
