what's a good chassis

Im looking for a good quality chassis. Every time I google, the only thing comes up is that Smart robot chassis. I have it and I have to say it is meh. I'm looking for a good quality chassis somewhere between $30-50.

Any recommendations?

Did you look at the chassis at www.pololu.com?

I sure did. But still don't know what's good to pick? I'm looking to purchase for a classroom though. So recommendation would be great. Something easy to work with a group of people.

Have you thought about old toy RC cars?

You really need to explain just what the bot is going to be doing for a platform to be suggested.
