What do you want to use it for?
EDIT: Sorry that question is unclear. What I mean is, I have it, but don't really use it. If you want a program to play against its ok (I mean it supports RHP) but there are better. I have Arena also, and it's great to analyze with, IF you know what you are doing. I didn't for about a month, then heard about PRO DEO (an engine) and am now able to analyze. I do have crafty, but for whatever reason using it on there has been a real hassle. Basically, I don't see the need for Rival. If you want something to analyze with and don't pay money then I say get Arena (which I think allows you to play against your engine, not actually sure yet
