I'm quite happy with my Centerpoint sniper 370. I think I paid 215.00 for it 3 years ago and am pretty sure you can still get them for 300.00 or thereabouts. I've shot it a bunch with no problems and it's accurate enough that you could literally head shoot squirrels from 40 yards with it. It has a machined aluminum chassis/track, adjustable AR-15 type stock and is fast, accurate and relatively quiet. I finally got out hunting with it this past fall and killed a buck and a doe with it and it worked as good as any crossbow could have. It isn't necessary to spend 1000.00 on a crossbow for deer hunting. There are plenty of fast, accurate, good shooting crossbows on the market for under 600.00 that perform great. Most of them come with crappy scopes so be prepared to spend a couple hundred more for an upgrade there. I ended up putting a Vortex Crossfire II speed adjustable crossbow scope on mine and it works as advertised.
