One bow I would strongly recommend for someone that wants something nice but not overboard for their first bow is a Diamond Razors Edge. It has a broad spectrum of weight adjustability with one set of limbs, as well as very easy to set draw length adjustments. The whole package is around $350. You are getting alot of bow for the price. The best piece of advice I can give you, is to go to a reputable archery pro shop. They will be able to steer you in the right direction, and will take their time to set you up properly. I would avoid any big box stores, they are a crap shoot when it comes to this kind of stuff.
