I'm going to give you some different advice. If you want a great bow for around 300 bucks set up you should buy a used bow. Check the classifieds on this forum and archerytalk. There are some great bows for sale especially this time of year.

I just sold a nearly mint condition 3 year old Hoyt Razortec fully set up with sight, rest, arrows, and STS for $350. I'd much rather have a good used Hoyt Bowtech or Matthews than a lower quality brand new bow for the same price.
