Just testing the waters fo if you wantone or not I would sugest one i have sold at least a couple hundred of. Center Point Sniper 370. Cheap, has been dependable for the price and get some heavier bolts for it like the Carbon Experss pile drivers and run a 125gr head, have seen groups of 2 inches at 40 yards.
If $ were not a consideration I would go Ten Point, they have been doing crossbow for years and have it figured out. Really like the balance of their reverse limb bows.
I have a Parker that is 10 years or so old still going put its third set of strings on it 4year before last.
Centerpoint like a lot of the bows has a 5 year warranty for the original purchaser. Ten Point, Mission and Parker are lifetime warranty bows for the original purchaser.
See you are in North East Dallas, go see David or Mariah at Cabela's in Allen and try out a few. they do the warranty work on bows that are brought back there for it and I know who trained them.
Steve and Josh at Outdoor Proshop in Garland has some Mission crossbows as well.
