I'm pretty knowledgeable in this field. Don't be enamored with FPS as your guide. It's a stupid number that means little. Just like digital zoom on a video camera or contrast ratio on tvs. TenPoint makes the best crossbows on the planet. And it's not even close. They are pricey though. I got a TenPoint Shadow Ultralight. It's simply amazing. It comes with everything you need. What astonished me was how easy it was to set up. It comes in a bow in 2 separate pieces. The limbs and the stock/rail. It takes 30 seconds to bolt it together. The scope that comes with it is already "bore sighted". I took it out and shot it at point blank. It was close. moved back to 20 yards. It was an inch high. I adjusted the scope. Shot it again at 20. Dead on. I moved back to 30. Dead on. I moved back to 40. 1/2 inch right. Adjusted the scope. Shot it. Dead on. Within 15 minutes, I was driving tacks at 40+ yards. I could literally hit a dime at 40 yards from a bench on EVERY shot. I've bowhunted my whole life and I would have never thought you could set something like this up so easily. Its simply amazing.
As for a beginner crossbow, look at Wicked Ridge. They are made by TenPoint and use a lot of their technologies.
Another thing TenPoint and Wicked Ridge have over other crossbows is their patented cocking mechanism. Spend the extra money and get their ACUdraw system. It's worth it.
TenPoint also recently bought the Horton brand. They are outstanding crossbows as well, but pricey.
