I was in the same boat as you. I have riffle hunted for years, and wanted to bow hunt. I had an old Bear Whitetail 2, but the draw length was too long, and i couldn't shoot worth a crap with it. I decided long ago that I would not get a new bow until I could get EXACTLY what I wanted. I spent a little over a grand on my set up. I riffle hunted from shooting houses, but I still had a treestand, so that was not a problem. But I also learned that it is colder on a treestand than in a shooting house. I had enough close, but HAD to get new boots. There was another $70 (found them on sale). After getting busted by two does before I saw them, I learned that scent is a bigger factor when you don't have the shooting house to contain your scent. There's another $40-$50 for scent elimination stuff.

I am not trying to deter you, I am just saying that there will probably be hidden costs that you did not account for. So don't bust your budget on just the bow.
