I was in your shoes (Well,I'm a oldr,but tight$$$)
Kept looking for a "deal".Saw lots of friends buy lower end Barnetts,Hortons,etc,and all were disappointed and became frustrated.
On the other end of the spectrum,friends were dropping over a grand on Ten Points.No way could I do that.And still eat.
I started lurking on the crossbow boards,asking questions,and LISTENING to those with REAL experience-not internet posers.
I wound up buying a new Excalibur Vixen off eBay for under $250.
Wound up dropping another $130 on accessory package,then $15 on a scope mount.
Mounted an old reddot that I had laying around.
I learned QUICK not to shoot at the same target more than once.

It shoots that tight!
It's taken me a lot of year (I'm hardheaded) but I've come to find that it's cheaper to buy the right tool for the job the FIRST time,instead of trying to save a few bucks.You'll just spend more in the long run trying to cheap it.Put what you have towards quality tools,and even if it delays the purchase,you'll be better off in the long run.Good luck,and ENJOY!
