I grew up traditional, got into a compound and then went back to traditional. After 20+ years away my son sucked me back into archery and the bow I shot so well in middle school caused me some shoulder pain. I bought one of these on ebay for about $120 - http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2060353.m570.l1313.TR0.TRC0.H0.Xpse+archery+wisdom.TRS0&_nkw=pse+archery+wisdom&_sacat=0. Not as nice to look at as my Bear but after I found a good brace height it shoots very well. There are many nice old bow on ebay as well. I can buy a nice old bow for what I would spend in an afternoon of shooting firearms.

I primarily shoot full length wood arrows. If I miss it is generally not due to the arrow. If I break a wood arrow I suspect that I would have broken any other arrow as well and I can often repair the woods, with full length you have extra shaft to taper and mount a field point again. It you make an order from an archery supply house get spare nocks, field points, a taper tool, and glues - if you shoot wood. If you want to shoot wood this fellow makes great arrows for a very reasonable fee - http://www.tradal-bows.com/index.html.
When I shoot archery I look at the target and try not to think about anything, if I do then that is when I miss.
