Used is a great way to get a top of the line bow at mid line prices.
If your wanting brand new, new technology at a moderate price can be had in the Reflex line-up. Some of the lower cost PSE's have all the specs I'd be looking for in a new bow.

Tune your darton up and then shoot it next to the one your considering buying. Then you will know if the money spent is worth the change (literally).
