Check out my reviews...I've tried quite a few. Really depends what you like (or think you'll like). I'd start with a vibrating one...then you can decide if you like vibrating or non vibrating more. Get a Grip/Love Handle is my favorite and is priced nice. Aneros are good as well.
I have an aneros and it does nothing at all for me. I decided to spend some money and bought the Nexus Revo 2. Let me tell you, not only does it vibrate but it also rotates which is what does the massaging. I like to play with my cock a little bit and get it hard first. Then I lube up the Revo 2 and slide it in. The the act of sliding it in gets me leaking. As soon as I turn on the vibrations and the rotations, it is like someone turned on a faucet. This is all without an orgasm too. The Revo 2 is definitely my fav and totally recommend it for those looking for a good solo toy.
