I think the classic smoothie is a good starting point. It lets you explore a variety of things - you get insertion + vibration and the bullet-shaped head allows for decent clitoral use. It's not the perfect toy, but if you have NO IDEA what you want, I think it can help send you in the right direction.
You could pick one with a g-spot tip, too.
I would just recommend getting a decent one that has a good range of vibrations (the first one I got was crappy and cheap and put me off trying other toys for a long time).
If you have some idea of what you want, go with that. After trying that one that didn't work for me, I eventually came back and had a better idea of what I DID need.
For those with intact hymens, and really, anyone, I think clitoral is a good starting point and I think the Ultimate Massager is really awesome for the price.
