I'm thinking of joining the Army Reserves. Pros/cons of enlisting?

I've been thinking about joining the Army Reserves coupled with picking up ROTC next semester. I've done a lot of research but there's only so much information on the Army/Army recruiting websites, and I'm sure there's much more to it than they let on. I've heard a lot of good things about it, such as the money for school and the training you will receive helping you with your civilian job. But on the other hand I've heard stories of enlisted soldiers/officers receiving nowhere near the amount of money that they were promised for tuition, monthly stipend, etc., on top of many other things. I would just like to know what I can expect, good things or bad, if I were to decide to join. Any information is appreciated, but as I'm looking for reasonably fine-tuned details, input from Army soldiers/Reservists is preferred. Thanks much.
