You could check around and find a decent youth/woman's used bow for yourself. They are not hard to come by if you check around. Kids outgrow bows all the time.

As far as stabilizers, there are a ton of them on the market. With an older bow such as your husbands, it might not be worth spending too much on any of the higher end fancy ones but don't waste your money on just lead weights either. If you decide on one, get one with some dampening properties.
