I've already mentioned the Sage in PM, as have a few others, and it's not at all a bad choice.
I just remembered another good bargain I know of in lighter bows. It's from Kustom King called the "Horsebow Express" Currently, it's available in 29 lbs. only, and going for $120.00.
http://www.kustomkingarchery.com/Horsebow-48/productinfo/4718/ I paid $180.00 for my 50#er,just before they went on close out. In any case it's a VERY light, smooth drawing, and nice shooting little bow...Sort of. Due to it's light weight, shortness, and shooting off the hand it is very..demanding. It tends to be unforgiving and demand flawless form, and it's a learning experience to get arrows properly tuned to it. I know that's typically considered to be bad, but after I shot it for a month and then went back to my Sage, it had forced me to develop much better form, release, focus, etc. I still keep it, and use it to sharpen myself up and play with now and then.
If you have the patience, and can do without rapid gratification, it may be worth considering.
The main reason I thought to mention it was the low draw weight, and the fact that my own wife had seen me shooting several different bows and was always content to watch. It wasn't until she saw me shooting that one that she came out into the yard, picked it up and said "okay, teach me..." Nevermind that it's a harsh, unforgiving little thing, it LOOKS cute, I guess?
I know that's a perspective that's far enough out of the box to be perhaps a bit crazy, but..when I post advice threads I personally like it when people post unusual perspectives.
