They all work.....Excalibur, Ten Point and Bowtech fit and finnish and barrles are first class. Horton is the chevrolet, long time market leader with good value, but going through ownership problems (just bought by Greg Ritz) Barnett is alot of speed for the money, but inflated specs and quality issues. Plastic or metal barrel is something to look at.
Crossbownation.com has many reviews. I live in the land of crossbows and play with all my buddies. Here is my 2 cents......they are intersting and a hunting tool, but nowhere near as much fun as my recurve and compound for year round shooting.
Good luck to you.
